Optical Audio Is Not Working with Onkyo Receiver TX-SR501
I can't seem to make the optical audio from Apple TV work with my Onkyo Receiver TX-SR501. The Onkyo has 2 optical audio lines in in the back. When I hit the "digital input" button on the front of receiver, I can select from OPT1, OPT2, or COAX. I currently have the optical audio line going into OPT2, but if I select OPT2, I hear no sound. Any suggestions?
Thanks,
Holly
