Why isn't my Sony Home Theater working right?

Question

O.K. I just purchased the Sony HT-DDW790 home theater system. I'm using my xbox 360 which is plugged into the system via optic cable. When i play, the sound is very good and it does sound like surround sound but the back speakers don't have any sound coming out of them. Are they not supposed to the way i have it set up or what? Please help.

Try setting your Sony HTB to Dolby Digital 5.1, then make sure your xBox is also outputting DD5.1. Make sure your HTB is expecting digital audio in on the input that you've connected your xBox to. (do this from the menu) If that doesn't work, try switching the xBox's sound output to other options, like PCM or bitstream.
