On my system, audio settings show no available sound card. However, as soon as I start pulseaudio
from the command line, everything works. Output from pulseaudio

00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)
Ubuntu 12.04 LTS precise, upgraded from Lucid LTS. Worked out of the box on Lucid.
Run 'alsamixer' in termianl and check if master sound is muted.
oo is unmute and mm is for mute.
This is just a guess, but maybe putting pulse audio in your startup applications might solve the issue.
