I have 4.1 speakers. Connecting with 1/8green and 1/8 black. When I used my old Sblive card they would work perfectly fine and all was good. I just tried using my onboard and the speakers work fine - but the subwoofer isn't really working. When I turn up the bass in EQ it just makes the speakers get all distorted with extra bass. The onboard sound is 6 channel so I was wondering if there's any way to make it realise there's a subwoofer? I've tried the program settings that came with it and everything.
