My living-room stack is straightforward: Samsung TV on ARC (NOT eARC - story for another day), Denon AVR-X1700H hidden in a closet, Apple TV plus a bunch of consoles connected to the receiver, and a Raspberry Pi 4 already doing Homebridge duty. When it comes to CEC, the Apple TV handles it like a dream, but every console behaves like it missed the last week of CEC school. They wake the TV, switch the input, then leave the Denon asleep so I’m back to toggling audio outputs manually.
