[clug-talk] Soundblaster 128 & Debian Lenny

I had a similar un-cooperative on-board soundcard which I ultimately
ended up blacklisting. I recommend you do the same by inserting the
following 2 lines into your file /etc/modprobe.d/blacklist :

# do not activate motherboard sound chip
blacklist snd-cmipci

(My soundcard modules was the via-snd82xx and I inserted the 2 lines
immediately following the block ending with "blacklist usbkbd".)

After that, reboot your machine -- no longer should modules snd_cmipci
_and_ snd_opl3_lib appear under lspci from the reboot -- these modules
actually prevented your SoundBlaster 128 from being activated. Now you
_should_ have complete sound from the get-go.

HTH, Hendrik
