I have recently bought a nice surround sound receiver and a great pair of speakers. The system is hooked up to my computer. I REALLY enjoy the quality of sound that comes through. It's just wonderful. I listen to music more often than anything, and this creates a problem for me! Only the front two speakers are used while playing back music due to the fact that almost all music now is not encoded with surround sound. I am looking for a way to duplicate the front right and left channels to the back left and back right. Does anyone know of a way to do this? I have looked high and low and can't seem to find a thing!
