Hello, On my newly build pc, I'm using the Realtek sound manager to try to find out why my front left/right speakers aren't working. Sub/center works fine. I swapped the left/right cable (lime green) into the sub/center jack and the speakers work fine. I'm just not getting any output from the lef/right jack. Asrock 970 Extreme4 motherboard, using the onboard audio. Any help would be appreciated. Thanks!

Oops, didn't see you were not using the front panel, I have had a lot of issues with realtek, I would guess maybe it's a problem with the MOBO.
