[CentOS] Isa Soundcard under CentOS 5

Hello,

Under Fedora Core 6 I used to integrate the soundcard of my notebook
with modprobe snd-opl3sa2. Now, after changing my system to CentOS 5,
I could not find this module for my isa soundcard any more.

# ls -al /lib/modules/2.6.18-8.1.1.el5/kernel/sound/isa/
insgesamt 24
drwxr-xr-x 3 root root 4096 27. Apr 04:09 .
drwxr-xr-x 9 root root 4096 26. Apr 18:15 ..
drwxr-xr-x 2 root root 4096 27. Apr 03:36 sb

Both system-config-soundcard and alsaconf, compiled from sources, don't
find my isa soundcard. How could I get my soundcard working under
CentOS 5? Thank you.


regards
Olaf
