Comment 18 for bug 433055

Ok here is my lspci
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

I also think that i accidentally discovered something that might help you tracking the problem. Except from skype mic which doesnt work i also tried to fix my microphone for rosetta stone through wine. I am using the latest compiled alsa but the default that linux had was returning the same results.

So in my search for making the mic to work under wine i realized that the problem is the same as skype. I installed the pulse audio volume control and pulse audio device chooser. What i found was tha from the pulse audio device chooser when i would open the sound monitor it would show that its receiving sound from the mic while the pulse audio volume control will show only i small steady signal of sound being received by the mic.

I dont know how the programming code is for both of these utilities but obviously if you can check how the device chooser works and gets the sound the only thing need to do is fix the volume control and that's all (in theory at least and in my mind)

Hope it helps
