Try running on dos to find out what the card is configured for or
read the card's documentation and that a peek at the card.

Well, the sound driver's  3.5  on rah have not received a lot of 
testing on non-gus cards however if you like feel free to download
ftp://rah.star-gate.com/pub/snd01041996.tar.gz

vat uses /dev/audio so you don't need  /dev/sb ;additionally, you 
can access /dev/audio or /dev/dsp like any sound card on FreeBSD.

With respect to vat , you will have to compile vat in half-duplex mode
because we don't have full duplex dma support for SB thingies.
Basically, if you download vat from:
ee.lbl.gov:/conferencing/vat/alpha/..
compile vat with the default voxware module you will have a half-duplex
vat.

	Have fun,
