I don’t know what it is, but before under raybuntu’s community build under libreelec and very recently under corelec everything was working fine.
When i boot up the box it would say pusle eight connected and i would be able to control my amplifier using just my ordinary box remote. When kodi would go to sleep it would turn my amplifier off and when it was activated again it would turn amplifier on.
It would also wake up the tv from standby if required. Lately it hasn’t been doing that, No message on boot up. volume up down shows an icon on screen turning kodi’s internal volume up and down. No tv connected or audio connected messages. Sometimes i can “force” it to recognise by type “cec-client” in the terminal. It however hangs half way through and i have terminate it but none the less i can start using my remote again.
How do i go about debugging this? has something changed since the last update?
It would be nice if people would at least say what device they are using.
CEC is handled partly through u-boot variables. We only build u-boot for our 4 Premium Devices which are C2, LePotato, KVIM and KVIM2. For generic boxes there is not much we can do.
This error sounds like CEC is/was disabled in Android or similar. Try the command Adam posted.
