I recently purchased the aforementioned mixer, but I can't seem to get my computer to process the input from the mixer. I installed the driver that came with the mixer and it appears in my audio devices, but there is no signal from it. I have a mic plugged in and I can see that the mixer's levels are processing the mic's input, but it is not going through to my laptop. I am not sure what the problem is and I would really appreciate any help. I am running windows vista 64-bit. I can supply additional info if needed.
