Summary:                    Microphone is not working on Sigmatel STAC9200
Description: 
I have a laptop Dell Latitude 120L with a HDA Intel Sound Board:
Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition
Audio Controller (rev 03)
that is recognized as Sigmatel STAC9200.
Sound is working great but the microphone is not working at all.
I think that is missing some control on alsamixer about Mic, because there
is no Mic's volume or sound control, only "Input Source" is present
(Line|Mic) and seems that it doesn't change anything about Microphone.

I tried to load snd-hda-intel with all "models" as you asked me, but
doesn't work either.
I uploaded the contents of "/proc/asound/card0/codec#*".
#cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.11.
Compiled on Apr 19 2006 for kernel 2.6.12-18mdk

Same problem on Acer TravelMate 3000 Series.
However I can only record by using 'arecord' tool, and it only works when
I turn 'capture volume' on in PLAYBACK, instead of CAPTURE.

I'm using ALSA 1.0.11.
