It seems I'm having a bit of a bug when I'm trying to output my terrestrial DVB-T aerial connection from EyeTV over AirPlay. When I play live TV on my iPhone I get sound and everything works fine, yet when I output over AirPlay to my Apple TV 3 I get no sound at all, zip, nada, it doesn't matter how loud I turn my receiver up. Here's my set up below: Apple TV -> Video output via HDMI to VGA cable to monitor. Apple TV -> Sound output via optical audio to an optical only receiver. MacBook Pro -> Miglia TV Mini via USB -> Eye TV current release version 3.5.6. -> iPhone Access enabled. iPhone -> AirPlay to Apple TV 3. In theory this should work, I'm getting video but I'm not getting sound from the Apple TV. I'm wondering whether I need HDMI audio to get audio out of EyeTV over AirPlay?
