[Lenovo-T430s]: Internal Mic does not work.

201202-10635

kernel: Linux 201202-10635 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Problem:
Internal Mic is detected and input meter changes but not from outside noise.
If you open sound recorder the recorded track is just static. Changing the input volume or pressing the mute microphone button does not do anything.

I've adjusted all the mic volumes in alsamixer to max, and that did not fix the issue.
