Or perhaps you want to play background music, but have standard window
sounds coming from a different set of speakers.  Or you want to implement
surround sound, or have a set of speakers in a different room, but
have a unified stereo interface on your computer.

I think that it would be nice to be able to glue sound cards together
to get the surround deal going.  I don't have a suggestion about how to
do it, but the current interface would require the app to open multiple
sound cards and understand what is going on...  Whereas the audio driver
could know where all the speakers are and split the sounds up to the
right places.
