Description of problem:
Right after the modprobe install the sb driver (a real soundblaster 8 bits
card CT-1850A) the mixer wont load so nothing is heard from the card.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.aumix-minimal -f /etc/.aumixrc
2.
3.

Actual Results:  aumix:  error opening mixer

Expected Results:  soundblaster volume being set corectly.

Additional info:

I just removed the sb16 bits card to install the sb 8bits card (486 slot
space issue).

Then I run the "sndconfig" program and I did hear both the test sound.  
Here the modules.conf file content:

alias sound-slot-0 sb
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null
2>&1 || :
options sound dmabuf=1
alias synth0 opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1

Which is correct.  But right after "sndconfig" the following message appear:
