First off, try to choose all models for the given codec (see Documentation/ALSA-Configuration.txt) one by one and test it. If some model provides mic work - post it here with the PCI SSID of your sound card.
Currently using alsa-driver-hg20080126. Sound output is perfect.
The laptop has 2 build-in speakers and a built-in microphone and three jacks in front: mic, line-in and headphones.
With: auto, acer, acer-aspire,3stack-dig I can record sound from microphone but the quality is atrocious so barely usable.
Did you raise Mic Boost?
Yes. I did try changing it as well but it was set to maximum (3) most of the time.
Anyway, show the content of /proc/asound/card0/codec#* files and the generated file via "alsactl -f somefile store". These will be helpful for further analysis.
With: targa-2ch-dig I have notice that the output is on both - the speakers and the headphone whereas previously the output was changed by plugging the headphones in.
Other options do not really make any difference apart from the number of controls in the mixer.
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Unknown device 0090
To be sure, provide the output of "lspci -nv" (only for this device) to see the PCI SSID more exactly.

Hope it help.
