RPI5 to control volume on my AVR via CEC

    Hello,

    I've setup an RPI5 with Libreelec. my RPI is connected via HDMI to my AVR (Arcam AV41) and the output on my AVR is a projector. I use my phone to automate the start of the AVR and the Projector and the RPI is always on.

    I added a remote (keyboard and remote) to the RPI and use it mainly to control the RPI when i m using it.

    I just want to control only the volume on my AVR via CEC but it doesn't work. I couldn't find a thread to help with this kind of setup.

    any recommendations?

    Thanks

    Have a look at Settings -> System -> Input -> Peripherals -> CEC Adapter.

    As you can see, you can only use one HDMI device as CEC target, and that's probably your projector.

    Other CEC devices only have an on/off/standby switch via CEC.
