Last night I played about 15 minutes of two HD movies with no video issues. No issues at all.

I’ve been using LE9.2 on my old NUC (i3) for a few days with no issues, although I’ve only played multichannel music and music videos (mostly HD videos with DTS-HDMA, TrueHD and Atmos).

You might want to check on your receiver what type of audio signal...

Just to be clear. I’m talking about the Player setting: Adjust display refresh rate -> Always

Apologies if I wasn’t clear in my original post with my loose description from memory.

I’m definitely getting DTS-HDMA Atmos etc displayed.

On a whim I tried the latest Milhouse generic build from May 9th and I am getting the same results. Researching further I found this thread where there is a comment with regards to passthrough issues and v5 kernels. I am trying to find a 4.19 kernel build and see if it has coffee lake drivers.

The official LibreElec 9.0.2 build (with Kodi 18.2) uses 4.19 kernel and works perfectly with my Intel NUC8i3BEK with HDMI Passthrough. Last Milhouse build with 14.19 also works perfectly (I think it’s build 311 from memory). Build with 5.0 kernel are bad for audio Passthrough.

Don’t forget to set Kodi to sync TV to Source otherwise audio Passthrough will fail.

I have NUC8 -> HDMI -> Denon AVR X7200WA -> HDMI -> Sony 4K TV (2018)

I compiled this LibreELEC Generic build:

...

Anyone wanna try it?

I’d be keen to give it a try. Should this be ok on an Intel NUC?

I’ve got a NUC8 with HDR TV and HDR content.

Have you tried the blacklist fix suggested by Milhouse?

Code

1. echo "blacklist snd_soc_skl" >>/etc/modprobe.d/blacklist.conf
2. reboot

No. I was hoping the official LE release would resolve the issue.

Thanks for reminding me. I may give it a try over the weekend.

The later Milhouse LibreElec 9 for Kodi 18.2 (Generic) test builds using Linux 5 have ALSA problems on NUCs (no Passthrough Audio). I’m hoping this will resolved with official LibreElec 9.0.2 build.

I’ve had to stay with last Milhouse LE build using Linux 4.19 to use Passthrough.

The LibreElec 9.0.1 MR release file does not exists when attempting to download:

libreelec-wetek_hub.arm-9.0.1.img.gz

Is the link wrong or file just missing?

It looks like it’s a few months away based on an email thread by Linux devs I found in a Google search recently. They were still discussing HDR implementation design early this month.

Best video quality is 1:1 pixel mapping without size calibration in Kodi. Using ‘Just Scan’ on LGs or ‘Full screen’ on Sonys removes the screen overscan and gives 1:1 pixel mapping. Size calibration will never give perfect digital video.

ok Maybe a stupid question.. I changed the Kodi resolution to 3840x2160/24 and it works fine.. but then when try to watch Live TV.. I can hear audio but no video... If I switched resolution back to 1080P/60 I'm able to play Live TV (audio/video) no problem.

So for Live TV do I need to keep the Kodi resolution to 1080P/60? Or is there a way to have the resolution in Kodi set at 2160/24 or any other and play Live TV without problems?

I’m no expert on Kodi Live TV but I doubt Kodi will upscale live video to 4K.

embeleco : This problem is only when you set the Kodi UI to 4K right? If you leave the UI at 1080p But set whitelist 3840x2160 your NUC should playback in 4K with 4K content.

LibreElec 9 with Kodi 18 currently does tone mapping HDR > SDR to show ‘correct looking’ colours on your screen. It does not output HDR. (Without tone mapping HDR 10 bit video looks washed out).

There’s a thread in Hardware here where chewitt posted that true HDR output is being worked on now but won’t make the LibreElec 9.0 release, but will make LibreElec 10 release and will probably make a future LibreElec 9.x release. So our best scenario will see HDR added sometime this year (hopefully sooner than later, e.g. in LibreElec 9.1 - but it’s too early for anyone to know for sure)

I’m using a Minix Neo A2 air/gyroscopic mouse/remote (wifi). Amazon sells these for around $25 and available online worldwide. It includes a wifi dongle and works with no config on my two NUCs (5th gen and 8th gen) with LibreElec 9, plug and play (although I haven’t got it to turn turn the NUCs on/off yet, the on/off button is IR apparently)

The gyroscopic mouse it really nice to use and no reception problems even it large rooms.

Thanks for the update. Sounds like a sensible plan.

Is there anyway/where to follow the progress of these patches?

Subscribing to this thread. Hopefully chewitt will post more updates.

Question: Will we see these Linux/LibreElec HDR updates in the new LE 9 at some stage or will we have to wait for LE 10?

I have a 8th gen i3 and no problems with LibreElec Leia viewing 4K UHD HEVC/HDR (tone mapping) content, 1080p video, HD audio via pass-through (Atmos, DTSHDMA etc), Multichannel FLAC 24/192kHz etc. All via 1GBE LAN from NAS.

Thank you wrxtasy!!
