Enabling Surround sound in ALSA
Surround may already be working, make sure alsamixer has the right volume settings (Wave Surround in particular).
These commands should be useful for testing:
For 4.0 surround (two speakers in front, two in the back):
speaker-test -Dplug:surround40 -c4 -l1 -twav
For 5.1:
speaker-test -Dplug:surround51 -c6 -l1 -twav
For 7.1:
speaker-test -Dplug:surround71 -c8 -l1 -twav
If it's not working, you might try following alsa's own guide:
http://alsa.opensrc.org/SurroundSound
And also this:
http://www.halfgaar.net/surround-sound-in-linux
Note however that many codecs require custom routing (ttables), the folk at #alsa on irc.freenode.org may be able to help in that case.
Enabling Surround Sound in OpenAL
Edit ~/.openalrc (or /etc/openalrc if you want the setting to apply system-wide) and add these two lines: `(define speaker-num 4)` `(define alsa-device "surround40")` Currently OpenAL does not seem to work with 5.1 or higher, but this should work fine.
