Intel HD audio in 2.6.28

[Lukas Hejtmanek]

Hello,

I noticed that Intel HD audio in 2.6.28 is a bit broken. I have Lenovo
ThinkPad T61 (AD198x).

The problem is that I'm unable to disable microphone routing to the speakers.
I.e., I hear myself from the speakers. Muting on microphone in playback devices
does nothing. Muting the Internal, disables the microphone completely. I think
this is a bug.
