Prior to tvOS13, my Apple TV 4K would turn on/off my Yamaha AVR and Vizio TV with the CEC commands. With tvOS13, the Apple unit will turn itself off and the AVR, but does not send the CEC signal to the Vizio. I have performed resets on the AVR and TV with the same results. Is this an issue with anyone else on tvOS13?
Apple TV 4K – HDMI 1 on Yamaha AVR
Yamaha HDMI out to Vizio TV HDMI 1 (ARC).
If I plug the Apple TV directly into HDMI 2 on the Vizio instead of the Yamaha, the CEC functions work fine (power on/off).
