arming an audio track
I have found that my audio tracks refuse to arm for recording. I cannot change the input channell from "none," and even using the computer's mixer device have I found an input that is acknowledged. Being a complete novice with midi, I have almost ceartainly overlooked something obvious, but I need to know what it is. I have followed what relevant advice I could find, but nothing seems to work. Help would be very much apreciated.
