Have you ever been to the Creative website? They say Surround sound right on the Audigy LS information.
Most newer motherboards have Surround Sound on the motherboard itself. I have a Soyo Dragon Ultra Platinum Edition and that has build in Surround Sound.
My Sound Blaster Audigy LS also has Surround Sound. It has three plug-ins. Two for speakers (one for two front speakers and one for two rear speakers, no front audio or bass output) and the final one is a SPDIF digital. There is also a RCA for digital as well. Those are the ones you need to get the full surround sound. You will need a receiver to decode the digital signal or a digital decoder.
