No Sound : request_module: failed /sbin/modprobe -- sound-slot-0. error = 256
 

Hi everybody,
I recently installed kernel 2.6.1 on my SuSE Linux 8.1 Prof - System. Nearly
everything works perfect.
But, I have no sound. All needed modules should be implemented the SndCard
needs the Intel8x0 module, which starts without Problems:

PCI: Setting latency timer of device 0000:00:1f.5 to 64
intel8x0: clocking to 48000

But when I try to start a SoundProgram(i.e. Freeamp) there comes this message
with dmesg:
request_module: failed /sbin/modprobe -- sound-slot-0. error = 256

But, if I start the modules snd-pcm-oss and snd-seq-oss with modprobe the everything works: Freeamp, KMix,etc.

And if I try to start an ALSA-Tool i.e. alsamixer I get the following message:
No Sound : request_module: failed /sbin/modprobe -- sound-slot-0. error = 256

Is it right that it has something to do with the modprobe.conf? I tried
generatemodprobe.conf that comes with modules-init-tools-0.9.13 but the error
remains.

Can someone please help me?!

By the way, these are the lines in /etc/modprobe.conf concerning Sound(I
think):

options snd-intel8x0 ac97_clock=0 enable=1 index=0
options snd snd_cards_limit=1 snd_major=116
install midi /bin/true
install sound /bin/true
