Hi, I've tried more computer orientated forums for solving my problem but they couldn't so I figured I'd try here. I'll start with my setup, I have an aux cable running from my desktop to my t-amp which powers my speakers and an aux to rca cable from my desktop to the sub. I've set it up as 5.1 in windows since if it's set as stereo there's no output to the sub. As a result when I play some games (Xcom, Skyrim, San Andreas) there is in audio dialogue when I use the 5.1 setup. I get all the background sounds, music, etc, just no voice. I'm pretty sure its sending the dialogue audio to the non existent center channel speaker which results in no spoken audio. When I switch back to stereo, I get dialogue audio but no sound from the sub and it shortly shuts off. I've tried getting a y splitter and connecting both the sub and amp to it and just plugging it into the computer and setting it as stereo. Which resulted in only sound coming from the right speaker. The only option I have left is connecting the sub to the amp with speaker wire, which I'd rather not do since it will end up being messy. Is their anything else I can do?
