I'm trying to use my external sub with the logitech z313 sound system, but it won't use the external subwoofer in conjunction with the speakers. I have the subwoofer connected with rca to standard jack adapter plugged into the back of my pc. The computer also detects it as well (I see it in the realtek audio manager and when you click "test" I hear the test audio play through the sub. Does anyone know if there's a way to make the speakers and the sub work together?

So my mobo has a dedicated sub output and the pc recognizes it's there (it plays the test audio), but for some reason no audio comes through it when I play music
