I have a gigabyte K8NS ultra 939 mobo. I bought new speakers to use with the onboard sound (I've been using headphones exclusively for about 2 months now). When I plug in the speakers everything works except for the middle slot (the front speaker jack). The speakers aren't faulty...tried them in another slot. I need to know is this a driver related issue? Or is there something I can download to fix this? I don't want to have to return the motherboard because of a broken sound jack...Thanks.
