I have a BackTrack4 installation running on a HP dv9000 that is
not outputting any sound at all. Yes, I know 5 is out, but still have some
use for this installation and would like to get the sound working again. I
have read a few long troubleshooting guides and rather than spend the better
part of a day trying to figure this out, I thought someone here might have
some insight. Sound IS working on the other OS's installed on this box (XP
and 11.04). Below are some commands and output. I would be grateful for
any ideas.
