[Pkg-alsa-devel] Bug#668470: alsa-base: Intel Corporation 82801I (ICH9 Family) HD Audio microphone not working (squeeze stable)

[Wirawan Purwanto]

Package: alsa-base
Version: 1.0.23+dfsg-2
Severity: normal


Ever since I installed Debian squeeze on my laptop (Thinkpad T400) the
internal microphone did not work.
I tried to tweak the volume settings via alsamixer, no sound coming out.
Tested recording with arecord or audacity, no sound at all.
Also the recording volume level meter on audacity did not indicate any
signal at all coming from the microphone (whether it is internal mic or
external one plugged via the analog mic jack).
Some people gave up and simply used PulseAudio, e.g.

http://forums.debian.net/viewtopic.php?f=6&t=76099&p=429287#p429287

but I think this error should be resolved so user can use plain ALSA for
the sound system if so desired.

I have tried kernel 2.6.38-bpo and 3.2.0-bpo and in both the mic did not
seem to work.
