Thanks a lot for the sample file!
I've forwarded it to the RPi devs, they could reproduce the issue and are looking into it.

Please provide a sample file (30sec-1min should do).

Dolby Digital Plus / E-AC3 passthrough is broken in kodi Garbled sound with DD+/EAC3 passthrough and official Dolby DD+ 7.1 sample · Issue #19182 · xbmc/xbmc · GitHub - until that's fixed disable DD+/E-AC3 passthrough in audio settings.

There is a post 19.0 PR fixing the default whitelist that may help (there is more fixed than the title suggest): Resolution: Try double refreshrate and pulldown also when no whitelist is set by fritsch · Pull Request #19382 · xbmc/xbmc · GitHub
Yes, I'm aware of that, and that will help with playback of eg interlaced videos on RPi4 - but it still won't help with stock default kodi installations where GUI is set to 4096x2160p30 or 3840x2160p30 - there are no higher res modes and no higher refresh rates. You need to switch resolution down to 1920x1080 so you can play back 50/60 i/p HD stuff.
Things will get better when 4kp60 output is supported in the driver (first version of patches already looks promising, but we're not fully there yet).

Just an FYI, you don't need a whitelist to use refresh rate switching, you just need the "Adjust display refresh rate" option enabled.
FYI: that doesn't work too well if display is set to 4k (which is default after plain install without changing settings) and max refresh rate is 30Hz. Kodi doesn't seem to switch resolutions (eg to 1920x1080 which will support 24-60Hz).
So on RPi with 4k TVs I very much recommend to configure whitelist correctly (and changing display mode from 4096x2160 to 1920x1080 is also a very good idea).

You can enable analog audio output by adding `dtparam=audio=on` to config.txt.
According to your kodi log you don't seem to have a whitelist set up and didn't enable adjust refresh rate. Make sure you do that, don't enable 25-30Hz rates of 1280x720, 1920x1080 and allow using double-rate refresh rates in whitelist instead. You are probably running in a 30Hz 4k mode and kodi doesn't cope with that too well if you try to play a 60Hz video - this is probably causing your audio sync issues.

To enable busybox's getty simply change busybox's target configuration to have CONFIG_GETTY=y - see here LibreELEC.tv/busybox-target.conf at master · LibreELEC/LibreELEC.tv · GitHub
You'll also need a systemd unit (and enable it) so getty is automatically started. In LE we remove getty.target and the serial-getty@ template, have a look at the latter systemd/[email protected] at main · systemd/systemd · GitHub as a starting point. Yu need to adapt the agetty options to busybox's getty options and can simply use a fixed device instead of a unit template and let it install to multi-user.target - the TTY settings in the Service block should be fine though.

This could be done via an addon, I don't think we have a getty in some addon though as that is an extremely niche usecase (building your own image and enabling the busybox getty applet and providing systemd unit files to enable it would be another possibility).
Keep in mind that a password on a serial console provides rather low additional protections. Once you have physical access to the device to hook up a serial console you could as well just take out the SD card and do everything you want (reading/modifying the data, enabling debug shell etc).
And if you go to the effort of securing physical access to the SD card you could as well secure access to the serial console pins - eg by putting everything in a metal box with a lock.

Better switch to nightlies, they contain additional fixes and it's good to get some additional testing of what will become beta2.

Thanks a lot for reporting back and I'm glad it's working now!
I expected that the video= option is needed, without it linux doesn't detect that AVR.
I'm currently working on a script to simplify this whole edid stuff - hopefully that should make it into beta2.
I'm not 100% sure why hdmi_ignore_cec_init doesn't seem to work - make sure everything's set up correctly in kodi's CEC settings (though CEC should only be ever used on hdmi0 in kodi/linux - so it's puzzling why your AVR turns on).

Yes - although I don't recommend using this build any longer, all changes are now in our nightly builds Index of / - if you don't get atmos passthrough with the official 10 beta1 version, use the latest nightly.

DerangedPineapple Pioneer edid loading (plus the associated video option for HDMI-A-2) should be enough - assuming you didn't have any issues with TV detection.
I mainly posted the example to illustrate that multiple edid files need to be supplied with a single drm.edid_file option (separated by comma) and video mode settings as separate options.
