    Just in case this could help to someone else, i've achieved it by building a custom addon and executing the commands in the following way:

    In keymap XML file:

    Code
    ...
    <key id="61625">RunScript(script.custom-cec-commands, volup)</key>
    <key id="61624">RunScript(script.custom-cec-commands, voldown)</key>
    <key id="61623">RunScript(script.custom-cec-commands, volmute)</key>
    ...

    In addon's script:

    Kind regards,

    I've playing around and found a shell command to achieve it:

    LibreELEC:~ # /usr/bin/cec-ctl --user-control-pressed ui-cmd=volume-down --to=0

    Driver Info:

    Driver Name : vc4_hdmi

    Adapter Name : vc4

    Capabilities : 0x0000010e

    Logical Addresses

    Transmit

    Passthrough

    USER_CONTROL_PRESSED (0x44):

    ui-cmd: volume-down (0x42)

    Sequence: 86 Tx Timestamp: 255.072s


    Now, if i map my remote's volup/voldown/mute buttons to execute the same in Kodi, i'm getting the following error:

    And then kodi crashes :-\

    Any tips on reason why i'm getting this error and how to overcome it?

    Kind regards,

    Hi all,

    I've a rpi4 directly connected to a TV (LG C1) trough HDMI with lib-cec enabled.

    I've an usb remote plugged in kodi and it works great within kodi.

    It has volup/voldown/mute buttons, and they behave as anyone would expect managing kodi's own volume.

    Desired behavior is to route those buttons to control TV volume instead of being captured and processed within kodi.

    While using my TV's remote, the up/down/left/right/OK/red/green/yellow/blue buttons are sent from TV and captured on rpi/kodi.

    Volume buttons on tv remote are processed in TV which is fine.

    Can I somehow configure it so that volume related buttons on rpi/kodi remote are sent and processed at the TV?

    Kind regards,
