I have the AppleTV connected to HDMI Input 2 and an optical cable to Digital Audio Input 2. No sound comes out of the receiver. I'm wondering if the remote is non-functioning as I get a lot of "No Data" messages after pushing buttons and the remote won't turn the receiver on or off. I'm trying to get to the On Screen Menu (I know I can't get to it over the HDMI connection, tried composite) but with no luck. There doesn't seem to be a way to get the OSM from the front panel to try and associate Dig Audio 2 with HDMI 2. Am I missing something obvious? Do I just have a bum remote?
