Hi Vincent.

Nice to see you now have the latest alsa driver installed. I'm not too clued 
up on mic problems, and my hda intel codec is different to yours (ALC662), so 
my alsamixer is going to show different controls to yours.

Anyway, be that as it may, my alsamixer shows 2 controls for the mic. Front 
Mic, and Mic, and both have switches to mute/unmute (M key toggles the 
mute/unmute). Logically for getting sounds out of the Front Mic, it needs to 
be unmuted, and the slider pushed up. Now you should get sounds from your 
speakers, when speaking into the mic (watchout for feedback, if the levels 
are too high). 

Now press F4, and you should see alsamixers capture controls. Mine shows 3 
controls. IEC958 (ignore that one), Capture, which has a slider, and beneath 
it a few dashes. To activate the control press the spacebar. The other 
control is for Input Source, and when on that control the up/down arrows will 
scroll through the source options. Mine shows, Mic, Front Mic, Line, and CD. 
If yours shows the same, I'd go for Front Mic. Push the activated capture 
slider up, and see if you can record anything from your Front Mic.

The model options for the STAC9228 codec,  alsa driver snapshot, dated 
20090118, are below. It may be worth trying them. You may find that some 
provide more controls on your alsamixer. Just add a line 
to /etc/modprobe.conf. Example below.

options snd-hda-intel model=ref      (that I believe is the default line)

Model options for snapshot 20090118 below.


STAC9227/9228/9229/927x
=======================
  ref  Reference board
  ref-no-jd Reference board without HP/Mic jack detection
  3stack D965 3stack
  5stack D965 5stack + SPDIF
  dell-3stack Dell Dimension E520
  dell-bios Fixes with Dell BIOS setup

Rerun the alsa-info.sh script again, and run it as below, and attach the file 
saved in /tmp to your reply, as it may be usefull to Takashi. I'm not an alsa 
developer, but he is, and may have a suggestion which will resolve your 
problem.

./alsa-info.sh --no-upload

All the best, and hope you resolve your problem.

Nigel.
