Hello, I have the same problem with this hardware audio:
"lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)"
After some search for the solution I have re-installed ubuntu and the sound come back ... until I install de modem software driver, that I really don't need. After uninstall this driver the sound come back again.
