Audigy Rear Speakers

In SuSE 9.0, do the EMU10K1 drivers support all of the speaker configurations that the sound cards handle? I have an Audigy2 ZS, but I had the same problem with my Audigy Xgamer. I cannot figure out how to get the rear speakers on. Everything works fine in windows, so I know it's not a hardware issue. Is there a setting somewhere.
