[SDL] Audio! More than 5.1?

I highly recommend FMOD (http://www.fmod.org/). I have no idea how
many channels it supports, but I believe it would make use of more
than 5.1, provided your hardware supports it. It's also highly
cross-platform, though it is not free (as in beer) for commercial

I've also integrated FMOD with SDL on windows, and been very happy.

Good luck.
