Hi,

After updating my WETEK Hub with the LibreELEC-WeTek_Hub.aarch64-7.0.2.Hybrid.CEC.tar I don't have HDMI-CEC any more.

How can I help in debugging this issue?
My TV is LG 42LB730V-ZD and WETEK Hub is directly connected to the HDMI3 while TV has a HDMI connection to the Denon AVR X1100W (HDMI ARC, DD and DTS passthrough is working).
Kodi log is not showing a trace of CEC related messages:

Code:

LibreELEC:~/.kodi/temp # grep -i cec kodi.log
LibreELEC:~/.kodi/temp #

while `dmesg` is showing standard line as far as I know:

Code:

LibreELEC:~/.kodi/temp # dmesg | grep -i cec

In Kodi I can't access Settings -> System -> Input devices -> Peripherals because it's greyed out.

Some assistance, please.

Firstly LG TV's belong in the special needs basket due to non standard custom extensions LG decided to add to the CEC protocol, LG called SimpLink There really is not much we can do when that happens apart from using a previous working version of LE in the interim until AML or the CEC Kernel guys sort out a LG workaround fix.

HDMI and ARC has been known to cause HDMI handshaking issues on AMLogic devices, that results in EDID checksum failures showing up in the Kernel Log.

Other symptoms of this failure include the peripherals menu greyed out and the inability to change the Kodi GUI to another refresh rate.

Suggestions include using non HDMI ARC ports on the TV. Disabling all ARC features, and even using non ARC or Ethernet channel capable HDMI cables.
