I have 5.1 Creative Surround sound for my computer and I'm running them through the on board sound card. When looking at the playback devices and doing the test everything works:Front, Center, Rear, and Bass. When I play something else with sound (music movie etc.) only the Front speakers and the Bass work. Its odd that the bass works but the center speaker does nothing since they are on the same audio jack. Any suggestions on the problem/possible solutions?
