sorry I'm only getting back to you now - I need to get a second HDMI-Mini cable.

With your workaround it works fine, but you have to make many changes to remote control.

To my knowledge, CEC signal is only at HDMI-0. So with the workaround CEC should work for the TV, but not for the AVR.

Is there a chance to override the supported sound modes for Libreelec forced - this would help ?

LE gets supported audio modes at boot time. To my knowledge, it's impossible to enforce a specific audio mode.

Another thing you can try with the old RPi -> AVR -> TV setup:

Have a look at LE's audio settings. Maybe you have to switch to a different output device (AVR vs. TV).

Or try this setup: RPi -> TV -> AVR. This is what I'm using.

We also have such a report for x86: Click!
So what I would like to know now: Does shutdown work with LE 10?

Thanks for the feedback. You can also try LE 12 Nightly. IF "Generic" doesn't work, try "Generic-legacy".

On SSH terminal for "LE 12 Generic":

cd .update
wget https://test.libreelec.tv/12.0/Generic/Generic/LibreELEC-Generic.x86_64-12.0-nightly-20230422-eb9ba2d.img.gz
reboot

or "LE 12 Generic-legacy":

cd .update
wget https://test.libreelec.tv/12.0/Generic/Generic-legacy/LibreELEC-Generic-legacy.x86_64-12.0-nightly-20230421-705e682.img.gz
reboot

However, even with 3840x2160@30 selected, the video, which says it is 3840x2160 HEVC, is still pausing. Kodi every few seconds displays the the "loading circle", it reaches 100% quickly, but playback is still not viable.

Does your HDMI cable also support 4K? They are often called HDMI 2.0 or 2.1 cables in the shops.

If not, then you get reduced data bandwidth, resulting in a reduced whitelist.

This is the same setup that I'm using.

Sometimes I get "Dolby Digital" output from a TV channel, so Panasonic TOSLINK is capable to transmit DD / DTS to the AVR.

Check this: When your LE box is off, go to TV's sound menu, and set "SPDIF Selection" to "Auto".

getut I don't say that it's working. Do you only have graphic issues, or no A/V at all?

Thanks for testing. I gave this thread into developer discussion, but no feedback so far. This makes me think, it's eventually related to your setup, and not a bug. Maybe LE uses wrong EDID data, provided by your TV. So I suggest to experiment with custom EDID.

PS: jernej just told me that he debugs HDR issues ATM. So if it's a bug, it should be found during the next weeks.

Thanks for testing. Please have a look at LE's audio settings now. The selected output device should include the word "Panasonic".

Maybe this GRUB option helps: Click!

In your setup are you able to pass-through DD 5.1 data from the RPi to the TV and then to the amp? Whenever I try that I don't get any sound at all on the other end.

Yes. Start problematic audio on your LE box. Then hit the menu button of your Panasonic RC. Go to Sound. You'll see an entry HDMI<NUMBER>. Switch that option to "Digital".

Digging around in the tv documentation and making a few tests seems to indicate that the tv s/pdif can also send DD multichannel, albeit from TV stations only (and not from HDMI inputs)

I also have a Panasonic Plasma, just with TOSLINK instead of electrical S/PDIF. Works fine with my DD / DTS AVR. So I pretty much have the same setup like you. I go RPi HDMI -> TV and TV TOSLINK -> AVR. That should also work for S/PDIF.

Is there anything specific I can test to try to provide more information or logs?

Unfortunately no. The only thing you can do ATM is trying an LE 12.0 nightly: Click!

So you know you're entering unknown territory.

Here is the link, just in case you don't have it yet: LE 12.0 Nightly Builds (RPi)

Seems like your Panasonic S/PDIF can only deliver stereo. So get an HDMI audio splitter with TOSLINK. It's not too expansive.

The other weak point in the chain might be your AVR. It's possible that the AVR can't handle 4K pass-through without losing audio data.

Can you try RPi HDMI-0 -> TV, RPi HDMI-1 -> AVR?

Users often have trouble when switching to 4K due to bad HDMI cables. Make sure to use HDMI 2.0 or 2.1 cables. So data rate will stay high enough to support all audio formats.

I did. There is not much information about current state of the support fot the current Ryzen APUs line-up.

Most users just grab their answers, and leave. You probably have to investigate for Ryzen on Linux kernel development. If it's in the kernel, LE will have it sooner or later. If you search for perfection, that's the way to go.
