Are the SB docs wrong? How can I test? 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. > Do I need to replace 2.1.5R's isa/sound/* directory with one from Rah > or elsewhere? Which rev is appropriate for 2.1.5R? 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 > With the stock sound/ dir, modified to use IRQ 5, like the kernel > config, it builds OK.

Do I need to create one? > 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, Amancio
