That's a dead end as many boards only had mono (single channel) inputs. Until we get the exact model board up on the discussion you are likely wasting your time.
I have a Gigabyte motherboard that has 2 microphone inputs. The Realtek HD Audio Manager shows them as front panel and rear panel and I would like to record 2 track stereo from them. I tried using Audacity but I only get 1 track at a time. Does anyone know how to do it in Audacity, or of another Win7 compatible application that will do allow me to do it ?
