I think you saw that in /usr/src/sys/i386/isa/snd/ instead... I can find no mention whatsoever of the Vibra16X in the sound/ subdir. I don't know what would need to be hacked to add this support to VoxWare, but you might want to take a closer look at the pcm driver's support for this card, either to see how it's done and add it to the VoxWare driver, or to use it instead of VoxWare. > Then it sets the 16 bit DMA to >4 making it so if you use dma channel 1 and <4 it says > that doesn't work.
