Hello,
I noticed that Intel HD audio in 2.6.28 is a bit broken. I have Lenovo
ThinkPad T61 (AD198x).
Is it a regression (I guess no) from any older version?
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.
Please run alsa-info.sh with --no-upload option with several mixer
states (e.g. internal mic switch on/off) and attach the generated
files.
"Mic Playback Switch" doesn't control the internal mic. It's only for
the mic jack. You should be able to mute "Internal Mic Playback
Switch", and this should be irrelevant from the capture path.
Make sure that your mixer app does anything strange...
thanks,
Takashi
