Ubuntu 9.10 has no audio

Last weekend I set up dual-boot Windows XP and Ubuntu 9.10 on my desktop. Everything went fine and I'm really liking Ubuntu so far. (A few years ago I dual-booted a desktop with Windows XP and Debian also, so I'm not completely new to this process.)

However, the only problem I'm having is that I have no audio in Ubuntu. It works fine in XP, both before I installed Ubuntu and now when I boot to XP with both installed. I had a look around Google and found a few people with similar problems, but none of the suggestions seemed to help.

I have two sound cards, one built-in and one additional. I originally bought the additional because I could never get the built-in card to work in XP. I had the built-in card disabled in the BIOS, and Ubuntu (with aplay -l) was only showing the additional card, as expected. I enabled the built-in card and Ubuntu picked it up, but setting the audio to use that card still had no effect.

The additional card is a Creative EV1938 (so it's fairly old).

I've run alsamixer for both cards and made sure all of the settings are at 100% but still no love.

Anyone have any suggestions?

Wow. There are a lot of people out there having problems with the EV1938 under Linux. You _might_ be better off trying the onboard sound, depending on what chipset it has.

Otherwise, does sound act like it should play, but just no sound comes out? Or if you try to play something (using, mplayer, for instance), does it hang and/or proceed very slowly? When you start trying to play a sound, do you get any messages in /var/log/syslog?

Oh, and because I've done this plenty of times: when you go into alsamixer and set everything to 100%, you are also unmuting all of the channels, right?

(Looks around...) There's also the Sound Preferences panel that you can get to by right-clicking on the volume icon in your notification panel. Worth looking around there and making sure that everything is correct--I think that once I had some card default to headphones-out rather than the normal output jack.
