I have the Biostar M7NCD pro MB in a Powmax case. The case has front audio connectors. I was going to enable them but on the MB there is a front audio header that looks like the wires should go to but has jumpers on it and in the Biostar manual, the labeling doesn't match. The case has: 2 mic ins, 2 ground, left in. left out, right in right out. The MB audio header has: mic in ground mic power audio power right out right out left out left out. I know Biostar has crap for tha manual. is the 2 right outs and the 2 left out an misprint in the manual?
