Somewhere between the 2.0.30+ sound driver and 2.1.54 (I haven't had a chance
to go thru the patches yet), support for my SoundBlaster 2.0 broke (not Pro or
16). For some reason, it looks like the sound driver thinks there is a mixer
on-board, but there really isn't. (It's basically just like the original Sound
Blaster but has slightly updated chips.. it was about $10 so I'm not

I'm going to check out the latest version on the ALPHA/BETA site to see if that
makes a difference.. no reference to this problem was on the website, so I
figured I'd ask here.

The odd part is that the MPU-401 support is in there even tho I explictedly
said "No" to anything related to it.

Here is /dev/sndstat from 2.1.54 (we should prolly make a sym. link to
/proc/sndstat someday):
