Hi, first post here!
I'm a part-time Linux user, with experience on Mandrake and Fedora.
 
After installing ubuntu 8.10, I find that my computer is very quiet, even when I don't want it to be! The only sound I can get is the beep when the arrow keys reach a limit, such as scrolling to the end of a list, or the end of a command line.
 
The master volume is high, I have permission to Use Audio Devices, nothing is muted, am I missing something basic??? I've been to https://wiki.ubuntu.com/DebuggingSoundProblems and lots of links from there. Learned a lot, accomplished little.  :)
 
I can turn off the beep (alert) in Sound Preferences, but I can't turn on other sounds, (Rhythmbox, youtube, etc.) Some info I picked up is shown below. I wasn't clear from checking http://www.alsa-project.org/main/index.php/Matrix:Main whether my sound card is supported by ALSA. The Intel soundcard list includes ESB2, but nothing else remotely like 631xESB/632xESB. If that's the case, am I screwed?
