Having just bought an Audigy sound card and some
speakers, I’ve been looking for easy ways to get
surround sound. Alsa does 4 or 6 channel sound
straightforwardly, if you can find stuff to feed
it with. It’s pretty easy to patch a couple of
SDL audio routines to get surround sound, using the
alsa driver.
I put the two small patches, an example multi-channel
.wav player (which does nothing special except ask
for the alsa driver), and example 4 and 6 channel
.wav files here:
