I have a dell vostro 1400, which uses the sigmatel codec (STAC9200)

It is working just fine with the snapshot, but I have to specify the model
in /etc/modprobe.conf. These are the results I got for all possible models:


# the position_fix parameter seems to end xruns in jack
# model=ref           - sound in headphone only, analog mic work. No digital
mic.
# model=3stack,5stack - no sound at all.
# model=dell-3stack   - sound works for headphones and speakers, no analog
mic. Digital mic is really too low (unusable for practical purposes).

Therefore, the one which works for me, is:

options snd-hda-intel position_fix=1 model=dell-3stack
