Hi every one,
I can't control Kodi (Libreelec nightly v18 0525, didn't work either on the v17) with my TV remote when the PI3 is plugged like this : PI3 --> Denon AVR X2400 (newly bought) --> LG C7V.
On the other hand, it worked if it's plugged like this : PI3 --> LG C7V
The CEC is active on both the TV and the amp.
I tried to change the HDMI port in libCEC conf to 2 because it's plugged in the port number 2 of the amp with no result.
cec-client -l gives me this :
device: 1
com port: RPI
vendor id: 2708
product id: 1001
firmware version: 1
type: Raspberry Pi
I don't know if I missed something in the configuration or if it's libcec that doesn't support Denon amp at all.
I've posted this here here also, maybe someone here could have an idea 
Thx
