Ahh yes, AC'97.. I think I've had issues with these before.... It's also the default device under VirtualBox and when I looked last we don't seem to control the "Master" channel.

Can you also attach "amixer -c0" (before running the below commands). More specifically I suspect that the "Master" channel is 0+muted or otherwise doing very little. A couple things that should get sound are: (as root) alsactl init 0 This should "initialise" your card to sensible default which should set Master to 55% unmuted. If that doesn't work, can you try "amixer -c0 set Master 55% unmute" Hopefully that'll get sound, but the correct fix is for me to fix this in PulseAudio...
