CEC and TV issue

CEC - Official Kodi Wiki

Settings for your CEC devices can be found in:

System -> Settings -> System -> Input Devices -> Peripherals -> CEC adapter

Depending on your setup you may not be able to solve the problem only through configuration options.

There are some bugs with libCEC library and LG televisions.

In this thread there is more information and some fixed images to download:

Wake from suspend (CEC)

Do yo have an LG TV?

If so, maybe you can try the image from this post: Wake from suspend (CEC)

Its Libreelec compiled against updated libcec and with this change reverting 256, fixing the LG input change when tv turned on · dbrosy/libcec@d9407d3 · GitHub that it's supposed to fix the problem of always switching to Kodi HDMI input.
Be aware that this image is only for RaspberryPi2/3.

To update you can follow instructions from : Update LibreELEC [LibreELEC.wiki]

It does sound like the same issue. Maybe try this build. (it includes the same fix as previously mentioned but i've also included the latest Libcec version.).

Hi guys,

I'm experiencing the same issue: when starting my LG TV (49SK8500), 4 or 5 seconds later the input source is switched to my RPi 3 / Libreelec / Kodi device and it's really annnoying.

For my knowledge: are this patches/fixes included in new versions / updates?

Thanks!

This is still occurring:

LG TV, Sony AVR, RasPi4/LibreELEC and a few other inputs into the AVR.

LibreELEC loves to steal focus, especially in the first 30 some seconds after turning on the TV, even if I switch to Satellite TV as input or another HDMI source, Kodi steals focus back, often two or three times in a row. Very annoying.

Any ideas anybody?

Thanks!
