Sound worked for me in Breezy, but in a completely new install of Dapper - no sound at all. I see many people all over the place struggling with this. After _many_ hours of googling, I found a simple workaround which works for me. It was described on: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2038
So basically what I did (as root): 1) Backup /etc/modprobe.d/alsa-base 2) Add to the bottom of /etc/modprobe.d/alsa-base: options snd-hda-intel model=ref 3) Reboot Voila! Sound works.
