So I just picked up a set of Logitech X-530's. I hooked them all up correctly, but when I play music through Windows Media Player, only the front left and front right speakers are playing along with the subwoofer. My old surround sound would play the music through all 5.1 speakers, as these should, but are not. What could be the problem? The speakers all work as I've tested them in the control panel.
I tested them on NFS Shift and the center worked, but very quietly, and the rear speakers still did nothing.
