It's possible that LE is trying to send a better audio stream, compared to the Apple TV stream. As a result, the HDMI data rate is eventually too high for the AVR. 4K@60Hz is already a lot of data.
If it's an HDMI handshake issue, it should be visible in the log.
I'm still thinking it's an LE bug, as mentioned in post #14.
Because nobody else cares, try to compile your own LE, and fix that bug. We have basic instructions here: Click!

Hmm, I'm using RPi3B+ with Panasonic TV, and CEC initialization works as always. Please provide a log after CEC has been initialized.
Upgrading from LE 9.x to LE 10+ needs an installation from scratch did you do that?
My Apple TV does 4K60 fine (and it shows correctly in AVR).
Can you try the same AVR port and cable for the LE device?
Super cheap also means super cheap software, and no chance to install other OS's. Something under 50$ should be OK.
I bypassed the AVR and it played fine with 4k60 but of course I need sound and HDMI switching.
Then your AVR or the HDMI cable is the problem. Most 4K material (not the demo) doesn't provide 60Hz at 4K, so you can ignore this for use-case scenarios.
The HDMI cable should be conform to HDMI 2.0 or 2.1 to play 4K.

Can you upload the log directly into the forum? it's at /STORAGE/.kodi/temp.
I attempted to upload logs, but it failed.

I've tried 5.1 and 2.0 with same result. At this moment it is 5.1.
Thanks. The test with 2.0 output channels was important to me.
Why bother about cables and receivers (which work with another source), when system don't even try to output 5.1?
We don't know that. HDMI negotiation is first, selecting a codec for the resulting connection is second.
Yep, kernel 6.1.45 is newer than 6.1.
How many audio output channels are selected on LE's settings?
What's the HDMI version number of your HDMI cables? You should try 4K cables.
Ah, now I understand. Then you have to write a cron script, which runs inside LE. elonesna has already described the idea. You definitely need basic programming skills to do that. To my knowledge, there is no plug-in for that purpose.
Your device probably uses an LSPCon chip to convert the second DVI output to HDMI.
Those converters have known issues. I think that's why it's not working. Sorry, no solution.
