I'm running 10.0 on an HP Media Center PC 873N containing an SB Audigy board.
Sound has been fine from initial installation a few months ago until suddenly there was no sound a couple of days ago. Reboot, no change. Reboot into XP and the sound is fine. Reboot into Linux, no sound.
I went into YaST->Hardware->Sound and the SB Audigy shows up as properly configured. I removed the SB Audigy configuration and then tried to set it up again. I got an error message saying that the module snd-emu10k1 cannot be loaded. Checking /lib/modules shows snd-emu10k1.ko, snd-emu10k1-synth.ko and snd-emu10k1x.ko
This is a problem I experienced as well. The problem isn't that the module never gets loaded, the problem is that when it does, udev fails to work. It never creates the device nodes in /dev/snd that it's supposed to create. That's what YaST looks for when it tries to determine if the module is loaded or not
I filed a bug for it, but unfortunately, the bug seems to be intermittant and fairly random, so it's very difficult to debug. On my last boot, I got the nodes (it may have something to do with the latest update of the kernel, not sure, have you updated?)
My system auto-updates everything but the kernel once per week. And now that you mention it the problem did first show up after auto-updating last week. When I reboot the system sound still doesn't work for me. -- Marshall Lake -- mlake@mlake.net -- http://mlake.net
