Running LE 11.0.6 on a Pi 4. Pi 4 is connected to a Denon X2400h via HDMI 5, Denon AVR connected to Panasonic OLED TV via HDMI 2 (ARC).
These are my CEC adapter settings after doing all the operations below. Note that it switch to TV as connected HDMI device instead of AVR as I initially set it up with no way to make the correct setting "stick".
Logs, with a comment at the beginning describing what I was doing before each log excerpt. All in sequence (i.e. did the operations one after the other without doing anything else in-between). Attached as a text file because it's too long to include in post.
How can I make it so that it all works properly?
