Pretty sure it's a SoundBlaster. I'll power down sometime, pop the box open and take a look.
I get this in /var/log/message file:
modprobe: Can't locate module sound-slot-0
modprobe: Can't locate module sound-service-0-3
Some time ago, I tried the "soundprob" utility, but very bad things ensued; my boot up hung and I had to edit a boot file in emergency
mode to fix it. Very bad.
