Ok folks, Got a Gateway 7510GX AMD64 with Kubuntu 8.10 and I got no sound.

Sound card is ATI IXP SB400. I've gone into KMIX and ensured nothing is muted. Tried several "Master channels" with no effect. I've tried sound everyway I can think of: via Amarok, CD, Pandora, movies, etc.

Got nothing. Any help would be greatly appreciated.

Went to the following site:

http://www.alsa-project.org/main/ind...Native_devices

followed the steps downloaded and unzipped alsa drivers, utils, plugins, lib, etc... I modified the /etc/module file as it instructed.

Initially, my changes seemed to have no effect, once I rebooted I seem to be good now. Amarok, headphones, Pandora radio through Firefox, and through movies. So I believe I actually fixed my own problem! Go figure!
