Okay, so I was trying to record last night, I was recording out of a digitech pedal through the audacity program. I double and triple-checked all the connections, and I can't figure out what was wrong because it wasn't recording. Suggestions?
check which input you're on, then in the upper right corner of audacity check to make sure the same one is selected.

If you dont know, just play selecting each one and see what works.
