[Bug 188972] Re: mic not working on dell vostro 1400 with hda intel (gutsy and hardy)

Dear ubuntu team, I've managed to fix my issue. 
Because I hope this can be useful to others here are the instructions to make it work.

snd-hda-intel takes some parameters, one of the parameter is the model of the card used. To read more about models, check /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz file and search snd-hda-intel. To see what model is used one can issue:
'aplay - L' or better 'cat /proc/asound/oss/sndstat'

in my case it is

SigmaTel STAC9228

So I checked back the ALSA-Configuration file and see there is dell-3stack driver that looks familiar to what I have. Then I added 
'options snd-hda-intel model=dell-3stack'
to /etc/modprobe.conf/alsa-base and rebooted (actually I guess just reload of drivers should be fine).
Sound was ok, but still no microphone worked in Sound Recorder (I tried Capture1, Capture2, Capture3, Digital) but when I opened gnome-volume-control, Selected Options (just make sure you have all ticked in Edit->Preferences) tab and changed Digital Input Source to Digital Mic 1 recording is fine using the integrated microphone in the laptop. 

My external mic does not work, but I do not care as the one integrated
is doing fine and I guess I can make it work by plaing with some source
of Capture combination. Anyway it would be nice if someone eplained what
is difference between :

Input source (gnome-volume-control): Mic, Front Mic, Line
Digital Input source (volume control): Digital Mic1 , Digital Mic2 and Analog
Record input from (sound recorder):  Capture(1,2), Digital, Mux

Issue is solved for me now.
