: I am attempting this sort of thing by using brute force- using two sound cards.
: I hav a GUS and a SB16, which can apparently be used at the same time.

I'm doing 16 bit 44.1khz bidirectionnal with a gus and sb16 with no problems.

Are you sure you have the SB and GUS on different dma channels?
They default to the same.
Also, I had to read and write from the same program -- just pipeing
srec to splay was a loss.
