I have an Audigy 2 and it works fine.
The only reason this might not be working, is something installed 
wrongly. How many sound cards do you have installed? ls /proc/asound, 
does in mention just card0, or also card1 ?

You need to have version 0.9.7 or both alsa-driver and alsa-lib.
Run "alsamixer"
Front speakers controlled by Master and PCM slider.
Rear speakers controlled by Surround slider
Center speaker controlled by Center slider
LFE speaker controlled by LFE slider.
alsamixer should also recognise "Audigy2" as the CARD,
Mine has a Chip: SigmaTel STAC9721/23
but the sound actually comes out of a different chip on the circuit board.
