I have a Epson EH-TW7300 projector, which is connected to a Onkyo TX-NR686 AVR, where the Apple TV and other devices are hooked up.
I often stream music via airplay to the apple TV, while the projector is off. This did always work fine and still does.
Often I will eventually turn on the projector to watch something on the apple TV. This has not been an issue before, the apple TV would still stream the music and greet me with a screensaver.
However since a recent Apple TV update (supposidly) when I turn on the project, I am greeted with a HDCP error from my Onky AVR, saying that the format is not supported. I still hear the music and sound of the apple TV, but i am unable to recover from this state. Rarely, I did manage to recover, but most of the time, i need to pull the power from the apple TV to recover. Turning off and on again the AVR does NOT help.
Any idea how to permanently fix this?
