It is very rare that you need to install a driver for a soundcard. oss and alsa support a very broad spectrum, but there apparently is a linux driver.
I downloaded the one from the realtek site: LinuxPkg_5.04.tar.bz2
Suse should extract it with right-click - extract.
(tar -xfz from the command line.)
There's an install script in there, so it should be just:
chmod +x install
from the command line in the folder you extracted...
or right-click - make executable
from within the file manager. Command line would be better though, as it will show you errors if they occur.
make sure to read the README file. In the linux world those are occasionally there for a reason.
