Capturing and setting persistent EDID data will prevent LE from seeing disconnect/connect events on the HDMI connection. This might help the AVR not loose sync, or it might not (my gut feel is it won't).
There's nothing to prevent you from using one HDMI port for video and one for audio. Just configure it.

Oh that's great ! What should I look for in the documentation to do that ?
I think you're over-thinking what's involved. Just configure a different HDMI output to the one being used for video.
Just plug the video into one of the HDMI ports, then plug the audio into the other. Then configure the audio to the port you plugged it into. No need to configure the video.

It seems that nothing changes.. I don't understand anything anymore
Yep, ALSA device list stays the same when you switch cables. To fix this, update your EDID from SSH:
getedid delete
getedid create

Ok I'll do that, and then I reboot with the two HDMI cables plugged in ?

Do this with your active (TV and AVR turned on) target setup. Reboot with the same setup.

Ok so i'm doing this with my TV and AVR turned on with target setup.
LibreELEC:~ # getedid delete
You don't have a backup file for /flash/syslinux.cfg. You did not use this script to create the custom EDID
Therefore we can't be sure the script is working properly. Exiting
LibreELEC:~ # getedid create
More than a single device connected. Probably enable "Disable all other monitors" at Kodi settings. Aborting!
LibreELEC:~ # reboot
I also retried with "Disable all other monitors" enabled at Kodi settings and I have the same messages.

Something I didn't notice before : my TV signal disappears after the LE splash screen.

I think that explains your problem. Is your AVR connected to a display somehow? In that case, the AVR would be recognized as another display option, which leads to confusion.
I've only been able to pull this off on *one* alder lake n-based mini pc. Of all the units that have dual HDMI outputs, only the Simodewa https://www.amazon.com/SIMODEWA-Mini-…y/dp/B0BZHKH2C5 (which amazon shows as currently unavailable) has worked for me. Not only is this the only unit I've gotten it to work on, you have to plug the display / AVR into specific ports, otherwise it won't work at all.
That said, the experience is truly enjoyable; mode changes on the display are instant, and the AVR 'locks on' to the audio stream with no issue, with the last caveat being the AVR can't be plugged into your TV (and therefore only supports 720p/1080p on the audio stream output).
Your other option is something like a VROOM device (assuming you also have gaming components you want to use).
Maybe it's enough to create EDID, only with the TV plugged in. Plug in the AVR afterwards.
