No audio ATI IXP SB400

I recently switched from SLED 10 SP2 to openSUSE 11.0 on my HP L2000 laptop. I had a few problems with installation. At first install, sound seemed to be working fine. Now, no sound. Each time I adjust the config on the device and it restarts the sound subsystem, the speakers will click, but no test sounds will play. Sound worked fine under SLED and Fedora, but I can’t get it to work on SUSE 11. Tried permissions issue with no luck. Any ideas?

You could try working your way through the openSUSE audio troubleshooting guide:
