You don't specify the setup, is it a computer one, or a full AV sound system? If its computer, there's usually an option in the sound card settings (creative soundcard?). Otherwise, there may be a way to make that work on the reciever amp, but its not too likely. I don't see a reason in playing music in surround unless its specifically produced that way for effect. When you hear a band play on stage, they don't play all around you, just in front of you. Surround is only really appropriate in movies and games. Ifs its a sorround recorded concert of a band, you should get sound from the rear, mostly the crowd I would think, but not ordinary CDs.
