First, check /proc/asound/card0/codec#* whether STAC9200 is identified properly? If yes, check the mixer contents (at best, run "alsactl -f somefile store"), see whether "Master Playback Volume" is raised, "Master Playback Switch" unmuted, "Front..." raised/unmuted, and "PCM ..." raised/unmuted, etc. If this still doesn't work, try to give model=ref option to snd-hda-intel. If it still not OK, please try bi-sect of git.kernel.org/perex/alsa.git mm branch...
