Greetings guys and gals!
I'm recording audio narration with the use of two Behringer C-1 Mics...Behringer Xenyx1204FX Mixer with the USB interface going into my Macbook.
I've had no issues until tonight where i'm getting all kind of static on the recording. I've changed the various cables...mics...i've plugged the mixer into a different outlet...still getting the buzz/static.
At first, the recording starts out fine...then around 1 min 20/30 seconds the buzz kicks in...we tried changing out various things after that started and now it just buzzes from the get go.
I'm pulling my hair out now...I'm definitely not a pro at this...and I just frustrated that the easy part (getting the audio) is turning out to be the hard part!
Thanks in advance for any advice.

Dec 19, 2007 10:50 pm More info to add:
I've also switched out Macbooks just to see if it was a memory issue...does the same thing on each laptop.
I've check/re-checked all the wires and connections. I don't think there is a "static FX" button pressed...although I wouldn't be surprised if some button is pressed that shouldn't be...but I don't think so.
I just pulled the USB cable out again out of the notebook and plugged back in. I re-set the inputs within the Macbook from internal mic to USB plugin. And I tried again...and wouldn't you know, my 2 minute test of rambling nonsense into the mic came out ok.
There is obviously something wrong but how do I pinpoint what my issue is? Is it on the mixer level? The usb converter from the mixer to the laptop? That converter box came with the mixer (and to be honest, doesn't look/feel like the most quality of products).
I'd just die if I were in front of a client now...i'm glad I found this out now instead of later. Again, I've had no issues with this till tonight.

Dec 20, 2007 07:09 am it's probably a resurse conflict with the usb device... if you have any other usb devices try unplugging them.
also just for kicks when the static occures... go to a command prompt and type
sudo dmesg
or type dmesg as administrator... don't think it will work as a normal user...OSX still should be unix enough to have dmesg.... post the output here...

Dec 20, 2007 09:33 am On guitar amps, I've seen a few times when the input jack will get noisy, needing a resolder, or a tightening. This may be the case with you, one of the jacks somewhere along the way may be getting iffy.
If you're using two mics, can you isolate the noise to one channel? if so, then you can keep eliminating possibilities until you only have one thing left: the culprit =).

Dec 20, 2007 09:46 am record the static so we can hear it too :)
Dec 20, 2007 10:32 am Thanks for the messages.
The only USB device plugged into the Macbook is the USB converter from the mixer to the laptop.
I've tried to isolate the noise by taking down one of the two mics at different times and it still does it. I physically pull one of the cables out of the mixer...and still got the noise.
I've got the audio recorded...and posted here: www.photographicnarratives.net/vault/test.mp3
It starts out find...then at about 1 minute mark it start to get the static. Later on in the night, the static got worse...and then just started at the get-go. The last few tests, however, the recording has gone fine even though I haven't really done anything...which doesn't make me feel that much better since I don't want this wild card when i'm in front of other clients.
As far as typing dmesg...should I type that while i'm still recording when the static occurs in real time? Also, where can I find the command prompt for the Mac? LOL. I'm a life long PC user and have recently switched to Mac...
Thanks guys for your help.
Dec 20, 2007 10:33 am And I have to say, the audio link within the forum is pretty darn cool. I thought it had omitted the link totally...
Dec 20, 2007 11:15 am Quick update. The static problem is still there. I can't hear it "live" as i'm recording on my headset. The only way I can tell at the moment is to stop recording and start the playback on the laptop within Garageband. Here is another sample of what is going on.

Dec 20, 2007 11:34 am If you are monitoring the mixer with headphones and you don't hear the static then it has to be something between the mixer and your soundcard. It really sounds to me like either a bad cable or dirty connections to your soundcard. Almost like they are not seated properly or are loose/dirty in some way.
Crap, nevermind, just saw that you connect via USB. Maybe dirty POTS on the mixer.... hmmm, not really coming up with any ideas for ya.

Dec 20, 2007 11:35 am ick, yeah that's bad. bummer.
I don't have much else to say, I'd be looking for resource issues first, but all my attempts would be PC based, not Mac based.
PCI latency, background services, things like that.
Sweetwater.com has a tech forum type thing, and they're real versed on the MAC line. Maybe get into their forums and see if you can find something.
Dec 20, 2007 04:51 pm Any possibility that this could be coming through the power outlet? I've moved areas in the room and it doesn't seem like it is doing the problem anymore, but until further testing tonight, I won't know if "moving" was an issue. Again, I haven't had any issues back in the area I was out until yesterday. I also keep thinking it could be the USB converter...is that something that goes bad and is that something that I can "upgrade" and replace?

Dec 20, 2007 04:59 pm Certainly, I've seen neon lights take down servers in car dealerships. Well, not take them down, but make the power bad enough that the UPS had a hard time staying constant.
A power conditioner would help that problem, though you lose the 'portability' of a laptop, at that point.
Yep, the UCA200 (i'm guessing) is just a analog to digital converter, taking sine waves, and making them bits and bytes. You could replace that with a Maudio mobile pre, or fastrack, or similar. You could move up in the behringer line, but Behr hasn't had the shiniest history.
There's a lot of devices you could replace the uca with, most are mac compatible, so you could just plug it in, load drivers, tell your software you have a new device, and off you go.
Now that I'm thinking, the UCA200 would get power from the USB on your laptop, are there any other items running on your USB bus? more than one device can tax out your USB power availability.

Dec 20, 2007 07:41 pm I tried typing those commands in the console but there isn't a place to do it...only a search function. I went to terminal instead which is where I got the message after typing "dmesg".
The other commands are not working or are not recognized. I must be doing something wrong. If I am to type this in console, where exactly?
Dec 20, 2007 07:43 pm pjk - no other items plugged in USB. Just my power cord and the USB converter.
Dec 20, 2007 08:21 pm just a suggestion, you might want to remove the stuff about MAC address and/or ethernet items for your personal safety. I don't know how easy it is to hack that sort of thing, but it's better safe than sorry.
Dec 20, 2007 08:27 pm Thank you. I hope I took out the correct lines.

Well there's your problem.
clock_get_uptime ()
It basically just returns the CPUs built in bus cycle counter. To work around this problem you can try to use a nanosecond based API.

Dec 20, 2007 08:32 pm yeah, the terminal must be what they call it... in linux it's called both console and terminal... basically 'the command prompt' thingy. :)
I can't seem to find any information on how you can display resource usage in OSX... but... the problem is the audio interface... so call Beringer's tech support and ask them about the two dmesg warnings...the clock_get_uptime and the 'too much audio data'... this may be a level 2 tech support issue so you may have to dink around with the first technician before you get to someone who can answer the question. :)... but I am very certain it's a resource conflict so hopefully they're more familiar with OSX than I am.

Dec 20, 2007 08:35 pm Also, you could also try using a AppleUSBAudio.kext from another version of OSX (assuming that's what you're running) and see if that works. If not then it's a USB issue and you should probably bring the laptop in to check for issues.
Dec 20, 2007 08:37 pm Nanosecond based API say what? LOL. Is this something I can just "fix" myself or do I sit on the phone with Behringer for a few hours tomorrow :( ?
Thanks for taking a look at this you guys.
Keith WarrenMans reach exceeds his graspMember
Since: Oct 23, 2007
Dec 20, 2007 08:44 pm Nanosecond based API is a bus speed tracking protocol. Never mind I said anything about that... I shouldnt even touch those things, lol.
If you have another USB microphone laying around, try it and see if you still get the the evil sounds. If not, call Behringer. If you do, it might be time to call mac.
Dec 20, 2007 08:46 pm I just remembered...it does the same thing with both of my Macbooks so it can't be the USB on the Macbook, right? All Behringer?
Keith WarrenMans reach exceeds his graspMember
Since: Oct 23, 2007
Dec 20, 2007 08:48 pm I dare say yes, Behringer.
Dec 20, 2007 08:50 pm Also, if anyone knows if I still have "sensitive" info on my post still up...I think I deleted the Mac Addresses...but I want to make sure :)
Keith...I wish you could have seen my face when you initially mentioned Nanosecond based API...I yelled up to my wife and told her I think I quit! :)

Dec 20, 2007 08:54 pm ... odd possibility... but is the macbook plugged into AC power?
but basically, no this is something Behringer ****** up. You're probably going to ruin someones christmas :)
What it looks like (in my 5 minutes of understanding) is that the device is basing it's 'speed' off of something that isn't reliable in laptops due to power conservation techniques.
Hopefully Behriger is aware of this and there's a firmware update (you might want to check) if not... heh... it's really going to suck. :)

Dec 20, 2007 08:58 pm The macbook is plugged into the wall...lol...it hasn't had an issue before...is that AC? DC? I dunno LMAO!
Dec 20, 2007 09:00 pm I don't mind leaving it up if it helps others as well if we find a solution. I'm just nervous cause I don't know what info is still there that can expose me. I'm currently planning out my strategy for contacting Behringer in the morning. I wonder if I should just send an email to their tech side first and try that.

Dec 20, 2007 09:03 pm I'm siding with zek, after looking around a little more, so long as your laptop is plugged into the wall, you shouldn't have any issues at all unless its a problem with Behringer.
DONT E-mail them. You'll be playing tag for weeks.

Dec 20, 2007 09:20 pm Thanks guys. I sent an "ask a question" just now...but i'll probably call them tomorrow...Ugh, not looking forward to this one. Spent 4 hours with Tivo for my mom over Thanksgiving helping her out...
You know, the hard part was SUPPOSED to be putting the project together...not in getting the audio into the laptop for editing!!!

Dec 20, 2007 09:27 pm ...and considering it worked earlier... it may be a configuration issue... but the way usb drivers are done who knows. Did it even come with 'Behringer' drivers? Almost all USB audio devices use Core Audio...
the reason I'd say try the online method first is because of the long distance phone call... digidesign used to be the same way...and they had me on for 6 hours once :P

Dec 20, 2007 10:47 pm No drivers that I saw. I just plugged the USB device into the laptop and then I went into Garageband on the Mac and switched the input audio from "built in" to "usb device."
Dec 21, 2007 07:44 pm Just wanted to update you guys on the status. I had emailed and called Behringer today and was expecting the long hours on end wait dealing with the tech dept.
Surprisingly enough, a lady answered the phone right off the bat and then transferred me directly to someone in tech support. We are talking under a minute...and, what, three days before Christmas???
Anyway, we went through a few different tests...he made sure all the items (mixer/laptop/etc...) were plugged into the same outlet...apparently if they were plugged into different ones that could cause a problem. I've never heard of that but I do what i'm told :)
Next, on my original setup of the USB converter (UCA200) I had RCA cables going from the CD/Tape output to the UCA200 input...and then just the USB connector to the laptop. Within Garageband, I was using "Built In" drivers for the output - my laptop speakers - and the USB settings for my input - mic and mixers.
He wanted me to attach a second set of RCA cables from the UCA200 output converter back to the mixer's cd/tape input. Therefore, I would be able to just monitor my recording and playback all on my headset.
Set up worked fine.
But I still got static.
So he wanted me to import audio into a different program - which I did - and I imported into Soundtrack on the Macbook. One time it recorded fine, the other, same static.
So now I'm in a holding patter till after the holidays. I just filled out the warranty information.
I'm in a satisfied mood - to a point - in the fact that I was able to contact someone so quickly. I just fear this is going to drag out...i'll have to send my mixer in to get it looked at...and of course they probably won't be able to replicate it...Ugh.
Dec 31, 2007 04:25 pm Hi bigebee, I'm having the same exact issue with my UCA200. I am also using the XENYX1204 with an Apple Intel laptop as part of an internet talkcast setup. I wasn't sure if it was a GarageBand issue or a Behringer issue. Hopefully this works out for you. I guess I'll follow your path and call Behringer. Please continue to post your findings here. I've appreciated reading your troubleshooting progress.
Jan 10, 2008 03:17 pm Hey Guys, just an update:
I did finally get my new 1204FX with UCA200 in the mail. I was quite impressed with how easy it was to get it swapped out.
I got everything hooked back up and the first recording went over pretty good. Then the second recording I had the static again. So now i'm assuming its not the mixer or the UCA200. I've switched USB ports on the MacBook Pro...and so far, it is working...but that doesn't make sense to me since the static issue does it on my other black Macbook.
So i'm not sure where to go from here. I'm keeping my fingers crossed that it continues to work...on the other USB port. I have to think there is either too much info/power/etc...getting pushed through on the USB port that it can't handle it...although it worked fine for months till my post.
I'll continue to post on this as more info becomes available.
RedzoneKC, let me know how your problem is going.
Jan 10, 2008 04:00 pm Well, throw what I just said out about switching USB ports...it's still doing it regardless of what USB port I plug it into.
Jan 14, 2008 02:30 pm I was given this msg from tech support:
"This may be due to a setting in the Mac OS audio control panel - regarding the selection of the clock source (either input or output)."
Not knowing where the clock source of an audio control panel would be, I skeptically changed my Date and Time in system preferences from automatic (internet) to manual.
And.... it has worked since then. So let's keep our fingers crossed that's all it was!
Jan 14, 2008 02:37 pm Wow. I was trying to find out how to contact you through the boards to find out how you are doing with your problem...and surprise, you just posted.
So they think the automatic date and time settings are the cause of the static? Wow, I have NO IDEA how that can be linked. Maybe someone on here can fill us in. I will try to uncheck the automatic update for time and date but this CAN'T be a legit solution??? LOL.
How long have you gone with no issue since doing this?
Jan 16, 2008 01:09 pm Hey RedzoneKC
I switched my date and time setting to manual as you indicated from your message and i'm still getting the static. I did notice, however, in "Audio Midi Setup" there is a drop down menu for "clock source" which is grayed out on "default." Is this the area where the Apple techs were wanting you to change? If so, anyone have an idea on how to change this?

Jan 18, 2008 11:33 am bigebee,
I have a MacBook Pro and I'm connecting to a Yamaha MW12 and I am experiencing the same static. I definitely think this is related to the Mac. I've also tried using a DirectBox to get a balanced connection to the MW12 but the noise is still there. So I'm anxiously looking for a resolution. Hopefully I'll find it here.
Also, I'm unable to change my 'clock source' in the 'Audio Midi Setup' as it is grayed out as well.
Jan 18, 2008 12:34 pm I feel your pain. My only workaround right now is to import the recording with Soundtrack...and then import that into Itunes the correct setting - 44.1 - so that it plays fine and I can edit in Garageband.
I hope one of us comes across a fix soon. I've tried everthing in changing the grayed out clock source box in my midi set up. Hopefully RedzoneKC can shed more light on what he did specifically.

Jan 27, 2008 03:36 pm Hi guys,
I´m new here, I was just looking for someone else with the same problem I have.
I´m also getting a lot of noise randomly while recording with my usb audio devices.
I have a Behringer UC6102 USB Guitar Interface and a Zoom 9.2tt Guitar Effects Console also connected by USB and I´m getting the following:
WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data.
WARNING: This USB audio device may not function properly. Please notify the device manufacturer.
From what I´ve looked so far, it seems that Tiger 10.4.11/ Leopard 10.5.0 / 10.5.1 and even 10.5.2 (beta) have the following at the AppleUSBAudio.kext source.
if ( (self->mUSBAudioDevice)
&& (false == self->mUSBAudioDevice->getSingleSampleRateDevice ()) // We didn't know this was a single sample rate device at this time
&& (kIOReturnOverrun == result)) // This is what IOUSBFamily should be reporting on an overrun
{
debugIOLog ("! AppleUSBAudioEngine::readHandler () - Encountered fatal error 0x%x on frame list %d (frReqCount = %d).", result, self->mCurrentFrameList, pFrames->frReqCount );
// [rdar://5417631] Drop a once-per-attach log message that the device is generating overruns.
if ( false == self->mGeneratesOverruns )
{
IOLog ( "WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data.\n" );
IOLog ( "WARNING: This USB audio device may not function properly. Please notify the device manufacturer.\n" );
self->mGeneratesOverruns = true;
}
flagOverrun = true;
...
...
if ( flagOverrun )
{
// This is a fatal error. Notify the AppleUSBAudioDevice to sync the sample rates when possible if this device has two streaming interfaces.
self->mUSBAudioDevice->setShouldSyncSampleRates (self);
}
goto Exit;
}
Tiger 10.4.10 doesn't have the flagOverrun property, neither the IOLOG Warnings WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data
So, best ideia is to check it with Tiger 10.4.10 to see if has the same audio problem or not. If not, then maybe I can change the AppleUSBAudio sources (for 10.4.11 and Leopard also) and compile them again like the Tiger 10.4.10 AppleUSBAudio version.
So, which os versions are you guys using ? Anyone with Tiger 10.4.10 to test if it works ok ?
Jan 27, 2008 05:32 pm I'm still stuck in "neutral" on this issue. Garageband + Mixer + USB = static problems. Taruga, if you come up with a solution, please let us know here.
thanks

Jan 27, 2008 07:30 pm Try this:
rapidshare.com/files/8716...ioTest.zip.html
Run it, it needs your root password since it will replace AppleUSBAudio.kext
A backup of the current AppleUSBAudio.kext is made to /
If you need to revert back, you just have to use Applications->Utilities->Terminal
and issue the following command:
sudo cp -Rfvp /AppleUSBAudio.kext /System/Library/Extensions/
Let me know if it gives you a better result, I´m also testing this one for the last 30 minutes with no problem at all, hope it continues like this :P
Jan 27, 2008 07:51 pm What does it actually do? You've given me a spark of hope! Will this
be overwritten again in future OS updates though?
I'll test tonight and post back here.

I was trying to compile the Leopard 5.1 AppleUSBAudio source but apple removed some important clock headers that prevents compiling. It can be fixed, but will take much more time.
The Tiger 4.10 AppleUSBAudio.kext seems to work fine in Leopard, so let´s hope it fixes our problem too.
And yes, it can be overwritten with future Apple updates.

Jan 27, 2008 08:11 pm You made me look at Webster's Dictionary for the meaning of "sneaky" , I´m Portuguese and I don´t understand some words. Now I get what you mean ! :)
Well, if it continues to work fine, then it means Apple was also 'sneaky' and caused us some unnecessary headaches
Jan 27, 2008 08:48 pm So we'll need to run this each time there is an Apple update? I wonder if 10.5.2 when it comes out will fix this USB problem? I'm getting ready to download and try this out...thanks!

Jan 27, 2008 08:57 pm I´m using a beta of 10.5.2, and it still gives me the same warning and sound problems. I mean, with 10.5.2 AppleUSBAudio.kext.
As soon as I get the warning "WARNING: AppleUSBAudio has detected that a connected USB audio device is sending too much audio data." the sound gets this kind of static.
Regarding the re-install after an os update, well... first lets try this with enough time to check if the problem is really fixed or not.
The replaced kext from my installer is still working fine, lets hope I put this issue to an end.
Jan 28, 2008 09:19 pm Ok, I've had a full day to test this out...well, not quite a full day, but off and on for the whole day :) So far, so good. I have not encountered the static issue. I'm going to give it a few more days to see what can go wrong.
Taruga, how is it going for you?
So if this is a fix, can anyone tell me what exactly we changed? Is it the USB drivers? And how can we get this reported to Apple for future released of Leopard? I wonder why this isn't more widespread too. Well, i'm happy with this temporary fix...it will be interesting to see what happens when 10.5.2 comes out...i'll keep posting back here as well.

Jan 28, 2008 09:33 pm bidebee, it´s going fine with me also.
What the program does is to replace AppleUSBAudio.kext with the one from Tiger 4.10
According to what I´ve seen at the sourcecode, apple changed AppleUSBAudio.kext in Tiger 4.11, Leopard 5.0, 5.1 and 5.2 (beta). So if, the version from 4.10 continues to work fine, then it seems this happens to be a bug from Apple since Tiger 4.11. Hope they fix it.
I don´t expect Leopard 5.2 to fix this, because the last 2 betas I´ve examined had the same issue.
Also, when Leopard 5.2 arrives, we will have to run the program I´ve posted to fix it again (unless apple fixes this till then)
I also have a friend with the same issue, he plays guitar with a usb device, and he has the same static problem. I will send him the fix to test it. He uses it a lot, so he will be a very good tester. Well, I´m happy with the results so far.
Keep me informed of any news. Thanx for the feedback
ps. To report this issue to Apple, go to: bugreport.apple.com

Feb 12, 2008 11:36 pm I need to know if the zip file worked. I have been following this issue on the apple forums and it has affected a lot of people.
I am using a Berhringer UCA202 and a Peavey PV10
Thanks
Feb 13, 2008 12:25 am It has worked for me so far. I haven't seen any other posts from Taruga so i'm assuming it's working for him also. Can you post where on the Apple forums you have seen this problem addressed at?
So far, the zip file works...good luck and please come back and let us know how it did for you.

Feb 13, 2008 12:40 am Thanks for the quick response!
I had posted on the Apple forum under this link discussions.apple.com/mes...6574750#6574750
There are more links on this issue. It seems to affect fire wire users also.
I had to go back to 10.4.10 , but there are updates that liked in 10.4.11. Too broke to get Leopard at this time. I am currently backing up my macbook and will run the update and then try the app.
I will let you know it it worked for me.
Thanks again.
Feb 13, 2008 01:06 am Thanks rgspro for the link to the apple forum. I just took a peek and indeed there are others suffering with the same problem but someone just posted today another "fix". I haven't tried it yet but i'll repost here for everyone to see. Again, this came from rgspro's link above:
I think we have a fix guys!!!!!
I e-mailed Alesis after the 10.5.2 update had no effect on the "random static" issue and received the following response today:
Hello Jason,
There have been reports like this from 10.4.10 to the present Mac OS as
Apple made a critical change in its Core Audio drivers with the Leopard
architecture. The way that we have found out to bypass this until Apple
addresses this in a fix is to change the Audio Midi Setup menu options for
input and output to 48k. I have attached a document showing how this can be
done.
Best Regards,
Justin Baro
Alesis Technical Support
In the limited testing I've done, the above solution has worked for me. Just open up the audio midi setup in your applications/utilities folder and change the default input and output to USB AUDIO CODEC and make sure that format on the input and output side is set to 48000.0 Hz.
Let me know if this works for all of you.
cheers!!!!!

Feb 13, 2008 02:21 am I tried the above 48k on the in and out. 28 min. into the recording, static. Ran dmesg and saw the too much audio error. Ran the zip file and currently testing.

Feb 13, 2008 04:17 am It´s still working fine with me, just to make sure, I´ve replaced AppleUSBAudio.kext from the original and after one minute I got problems again. So, I run my patch again and it started to work fine again. I will leave it like this. The 48k tip on the in and out doesn´t work for me and also causes me some latency sometimes.

Feb 20, 2008 09:33 pm I just upgraded to 10.5.2 so I went back to reinstall the "fix"...after inputting my system password, nothing happens. So I deleted and redownloaded from the link above...same thing...input password...nothing happens...just a blank window and the icon that looks like something is downloading or installing but nothing is happening. Has anyone run into this issue after the 10.5.2 update?
Feb 21, 2008 10:06 pm I too have recently encountered this problem but seem to have fixed it. I'm using an m-audio mobilepre usb and came across on their site that on macbooks and macbook pro's only one usb port should be used for music:
www.m-audio.com/index.php...1&keywords=
This seems like it might be true for all pre-mixer's, not just m-audio's. Anyways here's how it went down for me:
1) Using things just fine on 10.5.1
2) Upgraded to 10.5.2, then gband would record only 1/3 of signals being sent. IE there was a very periodic gap in what the computer was receiving.
3) Got latest drivers from m-audio. Problem not resolved.
4) I checked dmseg and was receiving buffer under-runs from the mobilePre
5) Downloaded another system update from Apple regarding the keyboard and "other fixes"
6) Problem still persisted. Came upon the m-audio page (listed above) saying to use only the farthest usb port for audio devices.
7) Recorded for two and a half hours. No gaps!!
Feb 21, 2008 10:41 pm Interesting article there Trojantrack12. However, I am currently using the USB port on the left (my left, same side as the poweroutlet) and have had the static issue there. I will try just for grins the usb port on the right side (although I think I have done this before with no luck)even though the article you mention said its not the one to use.
Also, I hope to hear from someone soon if they were able to get the file Taruga posted that reverted the audio USB files back to Tiger to work after this latest round of updates from Apple.

Feb 22, 2008 05:34 am Interesting but not a solution for me, I have 2 usb audio devices, a guitar effects console Zoom G9.2tt and a Behringer UC6102. USB port switching doesn´t help me. I´m at the moment with leo 5.2 and still using my proggie to revert back appleusb audio drivers. Seems to be the only solution for me at the moment.
Feb 22, 2008 08:54 am Taruga - are you able to still use that program? It no longer works for me. I even tried to download again and it doesn't work. Just curious if this has happened to anyone else with the latest updates.
TarugaMember
Since: Jan 27, 2008
Feb 22, 2008 06:47 pm Yes, I am... no problem at all.
Feb 28, 2008 10:34 am Taruga, thank you SO much for this patch.
zekthedeadcow, thank you for submitting the problem to Apple. I can't believe they released such a havoc-wreaking update!
Mar 10, 2008 04:58 pm Just to update,
Still having issues. Behringer told me to make sure the sample rate of the audio files iTunes was playing out was the same as the sample rate I had set up in the Audio/Midi settings for Audio Input, and that it was the same for the program I am using for recording (which is now Soundtrack Pro). So, basically, in my case, set every every everything is 44.1kHz/16bit.
Still no luck though. Haven't tried reverting the Audio driver with your ulitliy Taruga. Not sure my bosses want me to go that route. Still on Tiger, but Leopard should be in my near future.

Mar 11, 2008 07:41 am redzonekc, the utility simple replaces appleusbaudio.kext from tigers 4.10 one. So, if you´re have trouble you might be using 4.11, right ?
Well, you should try it, It´s apples fault. You should try it, since 4.10 I can´t get it working right without my 'patch' . I´ve tested Tiger 4.11, Leo 5.0, 5.1 and 5.2 and give me issues without my utility.
I can´t afford to be waiting for a solution by apple or Behringer or whatever.
I´m using one device by Zoom and other by Behringer, and my utility fixed the problem for me. So, I think it´s a problem with the apple driver as the hardware I have from zoom and Behringer doesn´t have any driver and relies on appleusbaudio from apple. I think your bosses would like the problem fixed, don´t you ? You can try it if you want, and if you have any trouble and can post another one to undo and leave it like it was. I´m happy, it´s working with me and I can record just fine, this was making me crazy
Mar 24, 2008 11:59 pm Taruga: Thanks for the patch. I tried it but it didn't seem to work for me. I'm using 10.5.2 and was recording with Audio Hijack Pro and I got the static again after installing the patch.
Apr 10, 2008 01:53 am Hi, I'm experiencing this same problem, but I'm using a USB headset and Skype. I'm talking and the person I'm talking to says that there is a ton of static.
I went to System Preference -> Sound -> Input Devices, and when I shake the cable of the headset, the bars on the volume meter go to full power like someone is yelling in it (hence the loud static noise).
Taruga, I installed your patch and then tried plugging in my headset. The computer wouldn't recognize it. Then I put the 4.11 version of AppleUSBAudio.kext back on it and it would recognize the headset, but the static was back. I once again tried putting your patch on and the utility won't run again for some reason (the gear in the lower left corner just spins).
Does anyone here have any ideas on how to fix this? Thanks.
Doug
Apr 10, 2008 09:42 am Hey Doug,
Sorry to hear about your static issue. I totally know how frustrating that can be.
Taruga's patch did work for me but after upgrading to OS 10.5.2, the patch doesn't install anymore. What's weird is that I am no longer getting the static after the upgrade even though people have reported that the problem wasn't fixed when 10.5.2 came out.
I even tried to re-download the patch and no matter what, the little beach ball still spins and nothing installs. I guess I should just feel lucky the static is gone although I wish I had an explanation on why its still working and why I can no longer run the patch.
Have you tried "dmesg" in your terminal? Do you get the same USB error message that I did earlier in this post? Also, try using different USB inputs...some boards I visited said it helps.
Hope you figure this out. When you do, please come back and post what you did to fix it.
Apr 10, 2008 10:50 am I typed in "dmesg" into terminal and did not get any of the error messages. I bought a two 3.5 mm plug (one for in, one for out) headset last night, because I don't think this problem is going to get fixed anytime soon.
I'm really fed up with Apple. In the past year, it seems every time I do one of their software updates something terribly wrong happens.
Days after my two year warranty, I did one and then my hard drive crashed days after that. Then I did another one and CDs longer than about 30 minutes were no longer able to burn (a lot of people had that problem too). And now this . . .
I hate going to a Windows machine, but this is just ridiculous.
Thanks for your help,
Doug
Apr 10, 2008 10:57 am I just looked at the dmesg code a little closer and saw this:
Sound assertion "0 != err" failed in "AppleLegacyAudio/AppleTexas2Audio/AppleTexas2Audio.cpp" at line 960 goto Exit
I don't know if that's anything or not, but it looks bad . . .
Apr 18, 2008 12:10 pm hi, i dont know if my problem is the same, but it sounds like it. I am using a behringer mixer with uca200. getting terrible slowed down almost distortion noise on playback and also sometimes when recording. I dont know what to do. Is this the same?
Apr 18, 2008 02:03 pm I'm kind of new here and I'm not using the same type of equipment as everyone else, but if you are trying to input sound through a USB port and get static while doing it, you have the same problem. Apparently those that are running any OSX after 10.4.10 (i.e. 10.4.11, 10.5.1, and 10.5.2) have this problem.
What you can do is run the patch that Taruga made (see an above post) and that works for some. Otherwise it seems you're SOL and since people have been having this problem for at least 4 months, I don't think Apple cares too much.
Let us know how things go, and good luck.
Apr 21, 2008 04:55 pm if i change to a firewire interface will that stop the static noise on playback?
Apr 21, 2008 05:25 pm Good question. I would think it is a USB issue with Apple and it wouldn't effect the firewire interface. If you find out for sure, please let us know.
Apr 22, 2008 05:18 am i cant believe this is happening, i jut bought an £800 laptop specifically to run daw software. Is there any news on when apple will rectify this problem?
Apr 22, 2008 05:21 am is it just me or does the link for the patch go to a software site for an audio test? am i being thick?
Apr 22, 2008 12:02 pm Yeah I don't know why it says "test" but it is a program that takes your apple drivers back to when they worked in the first place.
Dec 01, 2008 07:05 pm ...........so guys??? What's the conclusion to this?? Is the the Frogman's patch the only solution?
Dec 01, 2008 07:35 pm Hey there honeyguitar...
I have not come across any official fix but I have not had any issues with static with any of the new Mac updates. I'm assuming you are completely updated on all Leopard updates and are still getting the static? Any other bits of info regarding your problem?
Dec 01, 2008 09:13 pm ah this could be my long awaited solution. Thanks a lot....im going to start searching for leopold updates now. Finally I may be able to get my multitude of guitar riffs recorded! Thanks again
Dec 01, 2008 09:23 pm okay well im apparently as updated as one can be on the mac os x 10.5.5. What the hell? did i miss something when it came to my regular software updates?
Dec 01, 2008 09:56 pm You seem to be updated as you say. Are you getting the static right from the get go or are you getting it seconds into the recording? Did this all pop up at once or once you updated your OS. Give us some background on your issue.
Also, have you tried switching your usb ports? Some people have had success using the USB port opposite the power cord.
Dec 01, 2008 10:02 pm thanks for the quick replies. I have a macbook with only 2 USB drives both next to the power chord. The problem im having is that when I starting recording, it starts off crisp and perfect but then, randomly, breaks into a static fuzz whenever a note is struck. This problem has always been the case, regardless of updates. I've been browsing a lot of forums and it seems that it used to be a widespread problem.....but no longer. I'm using garage 08/04 and also have this problem in 'audacity'. Any recommendations? I'm hesitant to take it into the mac store as they charge you 140 bucks if it turns out to be software related.
Dec 01, 2008 11:57 pm oh, I'm also using an Art Tube project series preamp. I can find virtually nothing on the net with anyone who has had a similar problem with Art so i assume it's fine as I have had it replaced. I've also tried it on other macs aside my own e.g. Imacs at uni, friends. So is it some sort of widespread incompatibility with Art? Impossible! A lot of people use Art preamps and I cant find any complaints. I'm totally baffled. As i've said the tube works fine for any period up to 20 mins but then the static starts. Has these leopard software updates worked for everyone?
Dec 02, 2008 10:14 am Have you done a "dmesg" on your mac to see if you are getting the same error as I was? Scroll up to see/compare what I had posted with my error.
I'm pretty sure it is with your Mac. I replaced my Behringer mixer as well, and the same problem. After doing the initial Taruga patch, i've done all the normal mac updates and have not noticed a problem since but I haven't had a recording for a few months. If I get a chance today, I'll hook my stuff up and see again for you.
As far as taking it into Mac, if you decide to do it, take everything with you.
Dec 02, 2008 10:30 am how do i do a dmesg? It seems the Taruga patch is the way to go. Is it complicated doing this replacement? I've only made the mac switch a few months ago so im still learning :)
Dec 02, 2008 10:39 am I believe you type it in your "terminal"...do a spotlight search (top right of your screen) and then on the prompt, type dmesg after you run garageband and get the static. I believe someone noted how to do it above in the message string.
The taruga patch is straight forward...just click it.
Dec 02, 2008 06:00 pm thanks for all your help bigebee. It's really appreciated
Jan 08, 2009 01:01 pm I'm using garage band without any 3rd party software or hardware, aside from 3mm headphones, (i.e., i've been using the built in mic) and i've had this static issue intermittently for the past 6 months.
at first it was only when the computer was unplugged. but then one night i shut the computer down and when i started it back up in the morning the static was there consistently - slightly different than the "unplugged" static, but just as annoying. i finished recording for a few months, then came back to it and it was fine. Recorded for several days without an issue. Now, a month later, i come back to it and the static has returned.
I've tried switching outlets, unplugging other devices from the same outlet, changing the clock to manual, changing the audio midi settings to 48k (never worked - wouldn't allow me to change from 44.1k), running the taruga patch (though i'm not using the usb). Nothing has worked. It appears to be totally random. Any ideas?
Jan 08, 2009 02:08 pm That is odd you've gone a period of time and it was not there. Have you tried to do a "dmesg" on your Mac to get the exact error message after you hear the static? If you don't know how, refer to the above as we talked about it a couple time already. Please let us know how you fare in this.
Jan 08, 2009 03:34 pm ok...i ran it while i was recording (though it doesn't matter if i'm recording or not - just whether or not the monitor for the built-in mic is on). Not sure if it will shed any light, but here it is (w/ computer name omitted @ beginning and end)

Jan 08, 2009 06:27 pm Yeah, I don't see anything wrong in that report...but I'm not the propeller head some are here. If I come up with something I'll let you know.
Hard drive issues can crop up no matter the time...1 hour, 1 day, 1 year...i'm not sure why he would come to that conclusion though. I'd like to hear explanation as well.

is the actual error... It's some sort of disk error... might not be bad sectors...but a sluggish head armature. you night try doing a backup and reinstall of OSX to see if it helps.
Jan 08, 2009 06:38 pm Thanks Zek... and you think that could be causing the static?

Jan 08, 2009 06:42 pm I'm not really sure of the technical reason to get static, but basically the systems encounters bad data in the memory but keeps going...so it's unstable...

Path /.Spotlight-V100/Store etc etc etc. indicates that spotlight (which is a indexing utility) is probably getting hung up on a corrupted file... it could be a 'third party application' or a bad sector.
The solution seems to be to reformat and reinstall.
I'm not a mac user so I'm not really sure how spotlight works to know if deleting the corrupted file (if it could be identified) would solve the problem.
Jan 08, 2009 10:18 pm thank you both for the information. the fixes are going to have to wait for the time being, but i really appreciate you guys taking a look at it. i'll make a point of replying back when i have the time to try these.

I was experiencing static when recording on my macbook pro (PPC) running the latest rev of GB 8. I thought it was a hardware issue and finally read in the thread above and in other threads that it could be caused by a USB conflict.
So to eliminate this as a problem I checked all the sound setting applications (Line in, MIDI, etc.) I noticed that the program called "Line in" in my mac's Utility directory was set to a different input than the rest of the system level applications. (I'm not sure if Line in is part of the system or installed as part of another package I installed)
When i changed the input on the Line In utility to the input source I wanted or to system preferences my static went away.
Here's the link to the Line In app that i changed the settings in and it solved my issue. (again, i'm not sure if I had it because of another install I did and it started to create the problem once it was installed)
I hope this helps!
Mar 26, 2009 05:30 pm Taruga, your patch worked for me on Tiger 10.4.11 last year. I am about to install Leopard 10.5.6. Am I going to need to run that patch again? Please let me know, and if so, please send me the link again if you can. Thanks for your help!

Dec 31, 2009 05:49 pm Hey, I just wanted to say thanks to everybody who helped in this thread! I was getting the same distortion and I used the USBAudioTest file and haven't experienced any problems since! (I've only done about 4 minutes of testing though... I hope it holds up)
But yeah, thanks a bunch!
Jan 10, 2010 11:23 am Yep - another happy camper here: the "taruga patch" fixed the sync issues I was seeing on my 10.4.11 system. Big relief! Thanks!
Yes, I'm also interested to know which versions of 10.5 are "safe".
Thanks!,
Dan
