How can I get my microphone to work with my sound card? I have Yamaha DS-XG Legacy on board sound system. The driver is SXG50. The speakers work. The microphone is good-tested on another computer. The microphone is unmuted in volume controls and selected under recording. The multimedia properties list my sound card and I have checked use preferred device. There are two holes for plugs by the speaker connection. I tried both of them thinking they may have been mislabeled.
