[workaround and cause]

if you delete the file '/var/lib/alsa/asound.state' and reboot, the alsa driver is properly loaded. then, you can tweak the mixer settings to get sound (for me, i have to enable surround sound).

however, the next time you reboot, the sound goes away again and you have to repeat the process.

thus, i believe the problem lies with the alsa startup script. if the file '/var/lib/alsa/asound.state' exists at boot, alsa tries to load it but gets confused and alsa doesn't properly configure. maybe the file isn't properly formatted; i know it refers to controls that don't exist on my card.
