CEC TV Power Off is not properly recognized

    Hi

    I run LibreELEC 9.0.1 on a Pi3, connected to my TV (Sony Bravia something) via HDMI.

    I use CEC to control Kodi with my TV remote control. In general this works fine.

    I'd like to stop playback when the TV is powered off, so I don't have to stop streams separately all the time. This however does not work. TV power off is not recognized. As I don't see any key names in the debug log which I could manually map, I suppose there is already something missing at some lower level.

    I do see at least something in the log, when turning off the TV, so there actually seems to be some notification towards the Pi:

    Code
    2019-04-11 13:41:54.956 T:1650942832 DEBUG: CecLogMessage - >> 0f:a0:08:00:46:00:09:00:01
2019-04-11 13:41:54.956 T:1650942832 DEBUG: CecLogMessage - >> TV (0) -> Broadcast (F): vendor command with id (A0)

    But that's all. No mapping to button names or anything.

    I'm not sure where something is missing here... Just some configuration issue in LibreELEC? In Kodi? Missing low level support in libCEC?

    Thanks

    Michael
