I am running LE 10.0.2 on a RPi4 and come from LE 9.2 on which CEC was always working OK (Pi-HDMI-1 > AVR > TV)
If I have the Pi connected as: Pi-HDMI-1 > TV-HDMI-2 for video and Pi-HDMI-2 > AVR for Audio. Unfortunately the RPi looses it's CEC capabilities.
In some cases (but not entirely reproducable) if I reboot the Pi I get back the CEC capabilities.
1. as soon as I start playing audio/video it looses the CEC capabilities.
2. if I start playing audio/video with the AVR off it remains the CEC capabilities, but looses again when turning on the AVR
If I disconnect the Pi-HDMI-2 cable and direct both video and audio via Pi-HDMI-1, all issues are gone with CEC.
If the CEC capabilities are lost I get this info:
