So I'm running 3 cables out from my sound card into the multi input of my tuner. Everything works just great but I'm not getting any sound from my sub. It's driving me crazy.
If I use the THX surround sound tester window and do the noise test I get sound from my sub. If I use just the normal surround sound noise channel tester I do not. Games, music, movies, nothing seems to be getting the sound to work from the sub except THX applications.
