K I have a Pod Xt Live hooked up to my computer, how do I set Audicity up so I have a monitor, if you don't know what I mean, I want to be able to hear the input without recording, and hear the input when recording as well, how do I do this? It would help a lot of when I was recording it actually made sound because it's nearly impossible even if you know the song off by heart to play along to no backing track.

Please help I want to be able to hear everything while recording, thanks.
