[Techtalk] Four speaker support with Soundblaster cards

i think you might need to be running ALSA to get this to work - ALSA 
will allow multiple instances of sound (and mixers) to run, whereas 
OSS/Free wont....

although i've managed to get both my Turtle Beach Pinnacle and AWE64 
running at the same time, i've never tried sending them to 4 speakers (i 
just send them to my hardware mixer)...

the problem you might experience is latency between the two cards. a 
friend of mine was experimenting around trying to hard-wire a series of 
Soundblasters together to get 8 channels, but never had the time to try 
- the archives of the discussion are at the linux-audio-dev mailing list 

hope that helps,
