I'm forgetting how to do this and the answer is escaping me. I'm recording audio into vegas via a 1/8th inch line in and although the levels are clearly showing that a signal is coming in, i can't hear the recording while it's being recorded. After it's recorded, i can play the file on the timeline and hear it, i just can't hear it when it's recording in real time.
any quick answers? am i missing the obviouse here?
thank you
