We use a Hear Back System to monitor our sound coming from the PA system. The unit has a line out where I plug a cable to the line in on my Zoom H2 to make a personal recording. When I play the recording back through headphones, it sounds fine. However, if I play it through the line in on my sound card, all I get is a bunch of audible computer jibberish. (I can't think of a better way to describe it.) I also get the same thing if I copy the file from the H2 to my PC and play it back through Media Player ot iTunes. Any ideas on what I can do to fix it?
