I have a surround sound card, but PulseAudio uses just the front speakers!

Many people have a surround card, but have speakers for just two channels, so 
PulseAudio can't really default to a surround setup. To enable all the 
channels, edit /etc/pulse/daemon.conf: uncomment the default-sample-channels 
line (i.e. remove the semicolon from the beginning of the line) and set the 
value to 6 if you have a 5.1 setup, or 8 if you have 7.1 setup etc. After 
doing the edit, restart pulseaudio.

Never tried it myself, but guess that should do it. :-)

HTH, :-)
