Problem solved.

I came across 
where was suggested to throw away /etc/modprobe.d/50-sound.conf, and let 
Yast configure the soundcard again. For that problem it didn'nt help (it 
appeared to be a hardware problem after all), but in my case it solved 
the problem. While the old and new /etc/modprobe.d/50-sound.conf are 
exactly the same.
