Hey Ken.
Here is a very recent SMP HDR build done just before Kodi 19.3 was released that works for my NUC8:

I have been using the smp HDR LibreElec HDR build on my Intel NUC8i3BEK for quite a while with excellent results. Thanks smp.
Kodi Git has just added a fix for a long-standing issue that causes skipping in high bitrate Atmos streams. Skipping can be so bad some titles are unplayable (examples: The Beatles Abbey Road album and Free Guy movie) . This fix resolves the issue with changes to Kodi’s audio syncing.
Here is the Matrix branch fix, there’s one for V20 master too:
[Fix] Reworked TrueHD MAT packer to support high bitrate Atmos streams (fix audio dropouts) by thexai · Pull Request #20361 · xbmc/xbmcDescription Backport of #20339 What is the effect on users? Fixes audio dropouts playing high bitrate TrueHD Atmos streams on all platforms. Types of change…github.comsmp Would you be able to do a new build of your HDR LibreElec including this fix please?

smp Hi, I’m wondering if you could please do a new build of your HDR LibreElec release including this fix for Atmos skipping that’s now available:
Atmos Audio Dropouts with UHD-BD
This Atmos issue has been plaguing many for literally years in Kodi.

i may need to wait for subtitles to work in HDR mode as I need them
They work for me in HDR in #629 build

Hey HomerJau (Garry!)! If you don't mind my asking, what model NUC are you running LE10 on, and are you able to get HDR? If so, could you kindly let me know what buid or link to the download you use?
I installed the BETA2 from the main downloads and cannot get HDR on my NUC8i5BEK.
Thx!
Ken
No HDR in official LibreElec yet.
I’m using two NUC8i3BEH NUCs with the build in post #629 by smp and HDR is working well.
I’m hopeful the latest build a couple posts back today by smp will also do the job.
This is from current Kodi master:
LibreELEC-Generic.x86_64-10.0-devel-20210514171417-0f2dcbe.img.gz?dl=1
Excellent. Thank you!

smp Is there any chance you could please do another HDR build for LibreElec from the current (or recent) Kodi 20 master?
There were two committed fixes for 19.1 (and 20) around early April that resolve CUE file read issues in the Kodi music library. These fixes don’t appear to be in your LibreElec build dated 27 April.
I’m saying they aren’t included because using your build I have the CUE file issues these fixes resolve.
There’s at least two of us I know using your build daily that need the CUE fixes (discussed by personal messages). I run your build on two NUCs here.
Anything you can do would be greatly appreciated!

smp The build earlier today in post #620 looks ok on my NUC8i3BEH. I’ve watched two different HDR movies and they both look great to me. Blacks look black. Subtitles working now, HBR audio too.
Thanks for today’s build!
-
I'm not 100% sure about this. Someone tried my build with Kodi compiled from that branch some time ago and it didn't work for them, so I assume it works only on Gemini Lake.
I can confirm no HDR on your image 2 above on my NUC8i3BEH. I’ve gone back to image 1 that’s ok except for subtitles.
Does ffmpeg render subs?
The red subtitle block is just the video stretched to fit in the subtitle frame but shaded red.
-
The second one does not have the subtitle issue.
Thanks. I’ll try image 2 on my NUC8i3, but as you stated it may not do HDR on this system.
-
Thank you smp . Fantastic work!
I’ll test on my new NUC8i3BEH I built earlier today.
EDIT: Image 1 looking good. HDR, HBR audio, multichannel hires FLAC all ok.
Subtitles are a red block, unreadable.
Thanks again SMP!

Can anyone provide a link to a recent LE10 patched build with HDR and HBR audio working please? #502 the file has been removed.

I'd like to hear a valid technical reason why bitstreaming is supposed to be better than decoding to LPCM. Since Kodi can decode all known HBR audio formats and send LPCM 7.1 over HDMI I don't see a single good reason why anyone should bother with passthrough.
Kodi (and every other consumer software audio player) cannot decode Dolby Atmos to more than 7.1 and cannot place Atmos objects in their mixed locations in 3D space. This is also true for DTS:X. The only way to decode Atmos and DTS:X correctly is via HDMI pass-through to an AVR or AV Processor with an Atmos or DTS:X decoder onboard.

5.12 will work too. LSPCON HDR support was finally merged into kernel 5.12
This is great news! Linux 5.12 onwards will support Intel Kaby Lake graphics through to current. My NUC8i3 should be ok. I can now replace my NUC5i3.
The burning question: When will we see LPSCON HDR support in an official LibreElec release? LibreElec 11, I guess ?
I’ll definitely try one of the unofficial patched LibreElec 10 versions with HDR in coming days. Running Win10 and Kodi 19 on my NUC8 is horrible!
-
I saw a post (can’t find it now) saying Matrix will be released without HDR support. HDR will be added not too far after that apparently. Reason was to get Matrix out earlier, so add-on developers need support Python 3 earlier.
-
My new NVME SSD for testing arrives tomorrow. I doubt HDR is supported just yet. Kodi 19 release probably still months away.
-
There is nothing wrong with current Intel NUC's hardware. HDR support has just appeared in Linux kernel 5.3 and it is not yet implemented in Kodi.
The Milhouse Matrix (Kodi 19) LE alpha builds with Linux 5.3 have just started. I’ve ordered a new NVME SSD especially for testing these builds on my NUC8i3BEH. I’ll leave my current LE 9.2 SSD untouched so I have a fully working Kodi 18.4.
