HDMI eARC and CEC not working?

Quicksticks · January 9, 2021 at 11:45 PM

Hi,

I'm facing a few issues with my setup. I have a Raspberry Pi 4 Model B v1.2 running LibreELEC 9.2.6 together with a Yamaha RX-V4A AVR, connected to a Samsung Q90 via HDMI eARC (HDMI #3). I also have a Chromecast.

I've tried a few different combination but I can't make the TV remote control Kodi. If I connect the AVR to HDM1, it works just fine.

Here's my cec-client output, when the AVR is selected to Kodi. At this time, the TV does not see Kodi in the CEC list, only the Chromecast:

If I go to the TV and refresh the CEC devices available (only shows chromecast), this happens:

And still kodi doesn't show.

Am I missing some configuration or step?

Thanks

LE's CEC client works out-of-the-box. Make sure you have been activated CEC on your TV (External Device Manager, option Anynet+). Also check your HDMI cables, as described at your 4K thread.

Thanks, but what i don't understand is that if I use HDMI 1 in the TV it works fine, but if I move to the eARC, it seems that there is a request to stop the CEC on the KODI

**Da Flex** · January 10, 2021 at 9:06 AM Official Post

eARC is made for audio transmission, so I think CEC signals are left out by design.
