My Allegro library contains code for using the SB16 in stereo: check out 
ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2/alleg20.zip. Basically 
you set up your DMA transfer with a different command byte to the SB DSP 
chip (for a good list of DSP commands, look at the SBlaster docs: I found 
these on x2ftp, or can mail them to you if you can't find them). Once 
you've programmed the card for a stereo transfer you feed it twice as 
much data, with the left and right channels interleaved, eg. the first 
word is the left channel, second word is right channel, third word is 
left channel again, etc.
