Hi Portisch,
I was testing CoreELEC nightly N2 build on Panasonic Plasma and Denon AVR-X2000 - both devices very old and faced problems reported above.
Now I have connected N2 to Panasonic OLED TV and Denon AVR-X2200 - TV is manufactured in 2018, AVR also quite new model and CEC works as it should, except one small issue: once N2 is restarted CEC is “switching on” after around 2-4 seconds and 4 buttons do not respond: Stop, Pause, Next (>>|) and Previous (|<<) but powering off and on TV while HDMI 2 (N2) is active source brings back those buttons functionalities. The same was with Odroid-C2 connected to old Plasma Panasonic and old Denon so I’m pretty sure it’s Panasonic issue.
Now I’m testing CoreELEC on N2 connected to Panasonic OLED TV and Denon AVR-X2200.

Before Odroid-N2 I used to use Minix_NEO U9-H running LibreELEC-S912.arm-8.2.4.1.force.444.10bit available on https://github.com/wrxtasy/LibreELEC.tv/releases/tag/8.2.4.1 and there were no problems reported above.
Are those issues known for devs or should I collect some logs for troubleshooting?
