I was hoping that loading the module would have been enough.
Rebooting definitely won't help, because booting the first time did not
help either.
Maybe somebody else knows the solution.
BTW what do you mean by that oss was there? Did you already have a kernel
module named oss loaded. If you have some oss modules loaded that will
definitely screw up alsa. I had problem with that long ago, but it was
fixed before releasing sarge (so that discover blocks oss modules if alsa
is installed).
