HDMI passthrough doesn't work, not really
I have a TV in the bedroom, and an Apple TV 4K plugged into the 'media player' input in the 8801. I turned on HDMI passthrough, set the source to 'media player', and turned on HDMI control on all the devices. I set this up for my mom so that she can just tell siri to turn on the apple tv or do it herself, and the TV in her bedroom would turn on, be set to the correct input etc, without needing to turn on the 8801's zone 4. It doesn't turn on and off over HDMI CEC, so I figured HDMI passthrough was a good option but it doesn't work.
When I turn on the Apple TV with my phone (via the iOS remote app), both the Apple TV and the TV turn on, except there's no video or audio signal on the TV. If I then turn on Zone 4, I instantly get a video and audio signal. I thought the entire purpose of HDMI passthrough was for my situation where a video device just needs to send the signal to the TV without having to interact with the AVP. Did I misinterpret this or is there a setting I'm missing?
It's not the TV; I tried using the 1080p monitor I have in the equipment room that's normally used as "monitor 2" as "zone 4" and the exact same behavior occurs, which leads me to believe this is an issue with some setting on the 8801?
