I boot the box via PXE
That is the important information.
You are right, after disabling connman for netboot there is no DHCP client running any more after initial kernel configuration.

That is used frequently in LE. I'm only getting 0.5 points for C/P.
Use journalctl -u kodi-autostart to see the messages of autostart.sh.
One by one device or all together?
All together.
Is it possible that optical cabe is semi faulty and has problems only with centre channel? I can no imagine that...
HDMI, not SPDIF. Yes, it is unlikely to help but anyway worth to try.
To be honest all three suggestions are not derived from the issue but do solve prblens from time to time.
Try a real power cycle of all devices (pull the cord for >= 30 seconds).
If the issue persist pull and plug all data cables.
Finally try other HDMP ports and cables.
Have you modified the Downmix- Center Mix level?
There is already a fix for this.
I'm getting out of ideas, just a few thoughts:
- The 5500M driver is "amdgpu", to blacklist it use initcall_blacklist=amdgpu_init (or initcall_blacklist=amdgpu_init,radeon_init)
- You can add textmode to the kernel parameters. On successful boot you get a text console and i.e. can use dmesg and journalctl for further research.
- Check apple community HW forums if there is any linux support today for the MacBook.
Most likely you are on the master branch, use git checkout libreelec-9.2
The parameter is initcall_blacklist not initial_blacklist.
If this still fails try a Milhouse testbulid. Please read the first post of the thread. The latest Kernel 5.5 build is in post 618.
The graphics driver are part of the kernel and cannot be blacklisted via modprobe. Use the initcall_blacklist kernel parameter instead, see Radeon RX Vega 56 stuck at boot logo.
You need at least Kernel 5.5 and Mesa 19.3 for Radeon Pro 5500M support.
Access your device via SSH and use vainfo to check which acceleration is supported by your HW/SW.
Change the squash settings until no_root_squash appear in /etc/exports. Most likely it is "No Mapping".
