How are you installing the driver? Just modprobing the files on hand? Or actually unpacking the RPM? Its a matter of them being there, its just SuSe also has the ALSA drivers on hand and is loading snd-emu10k1 on its own, which honestly is just as good a driver as the Creative one, which is OSS based. It can do digital out too... Two ways to fix this... One, just go with the SuSe alsa drivers and run as root: alsaconf in a terminal and then run a mixer, any mixer, and adjust the sound volumes to what you like, and then run: "alsactl store" in a terminal and it should load everything you just did at boot.
Or... to stick with the creative driver.
and in there is a folder named: emu10k1, that's where the alsa drivers live. Delete or just move the folder somewhere like /root
Then run, as root:
And the kernel will forget all about the alsa drivers. Well, if they're currently loaded it'll still have them loaded, reboot and they'll go away.
