So I have a full 5.1 surround speaker system on my PC, and for whatever reason it only plays in stereo. When I do the 'test' thing in windows playback devices it plays the two noises out of the center, front and rear speakers. This would mean all the speakers (including the subwoofer, which outputs sound) works and are plugged in, it's just not playing 5.1. My headset is 7.1 and it has the 'Configure speakers' thing which lets me configure surround sound, so I guess there's something I need to do to enable it for the speakers? Thanks for any help!
