I bought an abit kd7 motherboard partly because it was ata 133 and part because it had onboard 5.1. but I can't normalize the sound that comes out of the front output. All other channels are at an amplifiable volume but it's like the motherboard is already amplifing the front output and despite everything i've done i can't get the volume to even out with the center and rear channels. Does anyone have any ideas? TIA!!!!
