To get you started, have you tried configuring it yet with yast?
YaST -> Hardware -> Sound
Do you see your sound card listed?
You could also try opening a terminal window (KDE konsole) and try running the command
alsaconf (as root user)
This should try to detect and configure your card for you.
If you are unsuccessful, then run this command
/sbin/lspci -v
and post the results.
BTW: Similar thread
here.
