Subject: ATX motherboard and SoundBlaster

Hi folks:

I have an ATX motherboard that has a built-in SoundBlaster with the
optional Yamaha Wave chips.  It doesn't have the SB Midi or the sb 16.
I'm trying to get vat to run.  

cat <file> > /dev/audio works great and mpackets received by the PC 
are process by vat and output correctly.  

The problem is that the mic.  A right click on vat results in the scale
maxing out whether a mic is plugged in or not.  I was able to get a brief
response on a remote system (ie the speaker scale maxed out for a second).
But after the first few packets (23 according to the vat stats).  It all
dies.  No more packets are sent unless I quit and restart vat.

Is it because I have the kernal probe for devices that aren't there?
The kernel recognizes that they aren't so that shouldn't be a problem should
it?  I'm running a 3.0-SNAP version (uname below).  I have a 2.2-SNAP 
kernel that works fine (but of course, that's on a different mother board).

Thanks
z

Here's the current config file:

# Sound boards for the built in ATX motherboard
controller	snd0
device sb0      at isa? port 0x220 irq 5 drq 1 vector sbintr
#The DSP 16 driver and the MIDI are not on the ATX board
device sbxvi0   at isa? drq 5
device sbmidi0  at isa? port 0x330
device opl0     at isa? port 0x388
options	SM_GAMES
options SBC_IRQ=5		#PAS-16. Must match irq on sb0 line.


Here's the dmesg for the board.
