mic socket only produces sound through one channel

Hi peeps. Another newbie with another (and probably easily resolved) problem. So please be gentle.

I have always used desktop PC's to record music, Using software such as Cool Edit 2.1 and Reason 3. When recording guitars and vocals I have always used the mic socket with no problems. The audio signal comes through both left and right channels. Sweet.

BUT

I have been forced, due to lack of space, to use a laptop computer these days and recently bought a decent sony laptop.

Unlike the desktop, when I use the mic socket to record on the laptop, the sound only comes through the left channel!!

Is there some sort of sound card setting that I need to activate in order for the sound to come through both left and right channels when using the mic socket? I use cool edit on my laptop, as I did on my desktop, but the lap top does not produce the same left/right signal. Maybe I need a different driver or something.

It's not just my laptop though. When I tried the same thing on my friends laptop, there was identical results. The sound only came through the one channel when using the mic socket too.

My laptop has a sigma tel high definiton sound card (thingy)

Please help me.

Thanks.

It sounds like you may be using a mono mic plug with a stereo mic jack. If so, you need a mic with a stereo plug, or a suitable adapter from Radio Shack.

a mono mic in a sterio plug should still produce a two channel signal because the ring and sleeve contacts will both connect to the sleeve of the input plug.

the solution should be to record a mono track using only the left channel... so when that mono track is played back it comes out of both speakers.

Ummm, no. From Wiki:

If a two-conductor plug of the same size is connected to a three-conductor socket, the result is that the ring (right channel) of the socket is grounded. This property is deliberately used in several applications, see "tip ring sleeve", below. However, grounding one channel may also be dangerous to the equipment if the result is to short circuit the output of the right channel amplifier. In any case, any signal from the right channel is naturally lost.

They're referring to amp outputs there, but the grounding applies to inputs as well.
