I'm not sure if other guests produce audio.  Know how to test this with
the dsl iso?

With dsl 0.8.1.1: # modprobe sb io=0x220 irq=5 dma=1 dma16=5 isapnp=0

This command runs with no complaints, and dmesg says
"SB 4.05 detected OK (220)", so I assume that works, although
dsl doesn't seem to come with any wav files that I can play
to actually test playing sounds.  Maybe I can pull one down
from the net.  But, if it detects and configures the device,
I'd mostly expect it to work.

Actually..  I catted /bin/grep > /dev/audio to see if I could
hear noise -- that didn't work.  Then, when I shut down dsl I
noticed this:

# qemu -user-net -enable-audio -cdrom dsl-0.8.2.iso
sb16: attempt to set DMA register 8bit 1, 16bit 5 (val=0x22)
sb16: bogus command 0xce

That could have happened when I executed the modprobe command
above.  Probably.  Seems like some kind of failure, but I
don't know the severity.
