CEC stopped working on Raspberry Pi 4

Hi there,
I’m running OSMC on a Raspberry Pi 4. After having done a clean reinstall of the December 2021 update HDMI CEC has stopped working altogether. The Rasperry is hooked up to an AV receiver which is turn is connected to the TV. (Samsung UHD). No changes to the hardware or wiring of the remaining setup have been made, CEC used to work without any issues. Unpowering the entire setup (Raspi, TV and receiver) at the mains as well as another clean reinstall of OSMC didn’t help.

From my understanding the CEC service seems to be running fine. I have uploaded the logs here:

Any suggestions would be greatly appreciated.

Merry Christmas!

On your RPi 4 are you using the HDMI port closest to the USB C plug? CEC doesn’t work on the other port.


Thank you! That did the trick :smiley:
Although I was pretty sure I was using the same port earlier…
