Comment 30 for bug 858412

I see others have steered you toward http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/ as the source for the 3.1.0-999-generic kernel.

Anyway, that solved the problem only momentarily.

Basically everything having to do with the mic on the webcam is unstable. At one point, Sound Recorder was working normally while Skype was not - a complete reverse of the situation I had before. Now Sound Recorder is back to "chipmunk" mode and Skype won't play back anything on a test call even though the input meter shows good sound levels coming in from the mic.
