The question is , can a standard windows sound-driver be 4-channel?
If not you either must have a 4-channel board with two pair of drivers with
2 channels each (can csound handle 2 soundcards?), or change csound to
directly use the card.
I have a Digidesign AudimediaIII card ( 2 analog + 2 digital out ), Cubase
Audio uses it with
special drivers, not standard windows.
I tried to record to a 4 channel wav-file from csound, and then split it
into 2 stereo or 4 mono for use with Cubase Audio or the Session program
that came with the board but I didn't have any program that
could understand 4-channel wav-files. But in theory it should be possible.
