I am on a 20'' iMac C2D and the microphone doesn't work. I am using
Alsa HG Head, which has all the sigmatel patches and pinconfigs
incorporated. I have observerd "arecord | xxd" for pretty much every
possible combination in alsamixer , but I only get garbage. I have
attached ioreg dump from Mac OS X of the audio stuff, amixer and codec
output for the audio card.
Any ideas for possible fixes?
