CEC suddenly stopped

    Hi all, and thanks in advance for your input and help.

    I’m running librelec 9.2.4 Generic x86_64.

    I’ve had a Pulse-Eight CEC adapter successfully in use for around 5 years. It even works the fire stick, so a real blessing.

    However it suddenly stopped working without anything else changing.
    I’ve not changed any hardware, not updated any software.

    I checked the obvious:

    • changed cables
    • Changed HDMI Port and USB port
    • Even bought a new CEC adapter
    • Restored to a backup when I knew it was working.

      when restarting KODI, the usually CEC message is displayed, then it says connection lost. It then cycles through those two messages.

      when I plugged the new CEC adapter in, the same behaviour occurs, except it also says the adapter needs a firmware upgrade.

      I’m not sure how to do the firmware upgrade, so I suppose that’s Q1.
      Q2 would be if there are any ideas thoughts on what could be causing this.

    The CEC device is running at Kodi:

    Maybe you have to reactivate VIERA Link in your TV settings. That's the CEC variant from Panasonic.
