Looks like LE can't deal with the screen mode you mentioned:

PS: Whoops, you have an RPi 4B, so you have no option to downgrade to 9.0.x. Write a bug report.

Can I do that without complete reinstalling?

Yes, you can. Go to the LE 9.0 download channel at the LE settings.

I already did the same procedure, and it worked fine.

I currently use 9.0.2, because it's the most stable choice for all RPi lower than version 4B.

I can test my German keyboard, if you still have issues after the downgrade.

Can you please downgrade to LE 9.0.2 for testing, and try again?

Downgraded and booted 9.0.2... Booted in to **SAFE MODE** still

Please provide another log file for 9.0.2.

It looks like broken composite PAL is a known bug:

raspberry pi zero w, kodi works with composite ntsc but it doesn't with composite pal

Can you confirm that it spins down on other OS'es? Some drives simply don't have the capability.

Anyway, I bought myself an single LCD display from Adafruit with HD44780 driver support. I still have to solder it, apply the LCDproc software, and we're good to go. Then I can also use the Pi without a TV monitor for listing to my music

Sounds like a plan! Let us know when you made it.

I currently do a little OLED project for my other RPi (headless Raspbian), that's why I'm interested.

The OLED also uses I2C, which needs a workaround if one already has a power button at the SCL pin of the I2C bus.

If you don't have a power button, then it should work without problems.

I say mostly because the "Audio Source" setting in this same section does NOT seem to stick. What I mean is I set the source to my Boss DAC. Then try a reboot and go to Live TV....it reverts back to "pi:HDMI".

Does it stick if you put hdmi_drive=1 back into config.txt?

Have a look at guisettings.xml, and check the video settings part.

PS: I just found out that guisettings.xml has no white list of supported screen modes anymore.

That's bad news.

The whole thing is just about a couple of lines of code.

The guy at raspberrypi.org said "The old stuff should still work - but don't expect it to work on an RPi4.".

So, it could be a compatibility problem, too.

In case that disabling passthrough doesn't help, my conclusion goes like this: Then your DAC doesn't support all audio codecs, and Kodi has no other choice than switching to the next audio output device (HDMI) to provide any sound.

You can buy a different DAC (HifiBerry) or an HDMI audio splitter (maybe cheaper) to get analogue audio for all sources.

Thanks for the good conversation, because you've been provided all info in an excellent way.

OK. hdmi_drive=1 was only for testing, you can remove it from config.txt again.

Your guisettings.xml says, you have audio passthrough enabled. Disable it at Settings -> System -> Audio -> Allow passthrough.

PS: The buggy file "mcp23s17.c" is a source code file, but the add-on only contains compiled files, so you can't patch it inside LE.

Da Flex where could I find these library file in LibreElec?

I think it's part of the LCDproc add-on.

Two options:

a) (easier) find another add-on / repo with the patched version (try the kodinerds repo)

b) (harder) compile a patched LCDproc add-on from source

The config.txt looks OK. The cause of the error message is a known bug, and you have to patch a file. Read here.

Good to see some progress. Please post your config.txt.

Do you have /storage/.kodi/userdata/LCD.xml present? Get the default version of the file here.

So you mean that up- and downgrading the system is necessary to install the newer ISA version while keeping all addons alive? Also, the posting said that buffering issues remained after doing this. Are those issues really gone after downgrading again with the latest libwidevine update?

The linked post was about the DAZN add-on. It had a buffering issue, which is gone since the latest libwidevine update.

Yes, you have to upgrade / downgrade LE as written in the post. It's necessary to get access to the newer add-on repo, which has the ISA version you need for Joyn.
