I have an M-audio Fast Track USB audio interface and it's been working fine since I got it last year: I recorded using it just last week, but today, when trying to record, no signal came through. I look in control panels and the Fast Track Out had some controls, but the Fast Track In had none. The problem occurred when I started using Mixcraft 4.5 but the problem, I discovered, extended beyond that one program. I usually use Cool Edit Pro and the device settings coincide with the audio interface. Did Mixcraft alter settings on my computer (not likely) or do I need new drivers?
