I am using Kernel 6.6.26 in Libreelec nightly build. Intel hardware is I3-8300 on Supermicro motherboard using Intel C246 Chipset. Working AMD platform is…
gitlab.freedesktop.org
Just discovered LibreELEC 12.0.1 Linux x86 64-bit runs kernel version 6.6.46..
Panther Lake I3 Gen12 GPU AV1 decode = CIR and PCON for HDMI - Any degrade in picture quality, any downsides in getting the Panther Lake???
Tiger Lake I3 Gen12 GPU AV1 decode = No CIR and Retimer for HDMI - I like booting from off state using CIR but this new model they removed it not sure why, even all the Celerons NUC 11 have no CIR only the Performance Panther lakes have CIR.
Also update the Windows HDMI driver. Those drivers include firmware, which can affect LE audio.
So I have been searching this forum and did find other posts saying the same thing, but it does not appear there are any HDMI firmware updates or update tools for the NUC 11 platform. Unless they are bundled in one of these?
When you have no audio or stereo instead of DTS-MA, try wiggling both ends of the hdmi cable when the file is playing. If that doesn't help, try another cable. This is just an idea since I had similar problem, and a new cable fixed it for me.
So I did try this with no improvement, and I don't think the cable is to blame since I can replicate my issue repeatedly with no physical interaction
I updated LibreELEC to v12.0.1 and also the BIOS which I found Asus released Version 0056 on 2024/08/20 - still no difference.
The video file I played in the attached log file of my original post I was actually able to hear audio yesterday, and I saw that my AVR was displaying DTS-MA while doing so. However today, I tried playing that very same file and it is not cooperating and my AVR is staying on Stereo not switching over to DTS-MA.
Is there test functionality I could use to command my AVR through Kodi to switch audio decoders? Maybe test files or something?
The Displayport selection is likely a non issue. Your NUC like uses a Displayport to HDMI 2.0 converter (AKA LSPCON) internally so Libreelec will see Displayport.
Any reason you are using bitstreaming? For your 3.1 speaker config providing Librelec outputs 3.1 OK there is no advantage to bitstreaming whatsoever, Libreelec/Kodi will decode to multichannel PCM with no quality loss at all. The main reason people use bitstreaming is to allow passthrough of DTS:X and Atmos data which Kodi cannot decode but if your setup is 3.1 that is irrelevant to you.
If you really want to fix bitstreaming it might be worth checking if an HDMI / LSPCON firmware update is available for your NUC. It is also worth trying one of the Libreelec nightly builds because they have a newer Linux Kernel which introduced a bitstreaming fix for LSPCONs which might fix DTS but wont fix the odd detection of DTS bitstreaming support without Dolby bitstreaming support.
Is bitstreaming the same as audio passthrough? If so, I found that unless I have audio passthrough enabled, I do not hear anything.
Is hardware firmware updates the same as UFEI/BIOS updates? I will check to see if my NUC is most up to date, thanks
Current setup: Intel NUC 11 Pro NUC11PAHi3 running LibreELEC 12.0.0, connected via HDMI cable to Denon AVR-2112CI in 3.1 speaker configuration, video output to a ViewSonic projector
My issue is that when playing downloaded files from my NAS that are encoded with DTS or DTS-MA, the video plays but there is no audio. I have GUI Sounds enabled always, so when this happens, I notice immediately that I no longer have any audio at all. I have to reboot to get audio to work again.
No issues playing Dolby encoded files from what I can tell
Current Settings > System > Audio config that mostly works for me:
AUDIO DECODER
Audio Output Device
ALSA: Default (HDA Intel PCH ALC256 Analog)
ALSA: HDA Intel PCH, ALC256 Analog
ALSA: HDA Intel PCH, DON DENON-AVAMP on DisplayPort #0

ALSA: HDA Intel PCH, HDMI #3

AUDIO PASSTHROUGH

Passthrough output device:
ALSA: HDA Intel PCH, DON DENON-AVAMP on DisplayPort #0
ALSA: HDA Intel PCH, HDMI #1

ALSA: HDA Intel PCH, HDMI #3
Dolby Digital (AC3) capable receiver: True
Dolby Digital Plus (E-AC3) capable receiver: False
DTS capable receiver: True
TrueHD capable receiver: False

I've tried default settings, but what I noticed is that unless I have Passthrough Audio set to True, I will not get any audio at all. At wit's end here!

Great news! Until LE12 is released with that fix (or maybe 11.0.2 will have it?), How can I tell what kind of audio stream a file has to see if I can notice a pattern? Thanks!
hdmi audio getting lost everytime you play and stop media is kinda a basic no-go
I am also experiencing this issue on my NUC 11 Core i3, latest stable LE 11.0.1. I leave mine running full time with no sleep or power savings enabled
Audio is normal the whole episode or movie, but on next play there could be no audio. I cannot reliably replicate this though! I can sometimes play multiple episodes back to back no problem, and sometimes I lose it overnight when I go to play something the next day. Or when playing the next episode of the evening.
Hi, I find that there are lots of selections available in a few Context Menus that I would like to remove, such as Browse Into, Play Next, Add to Favorites.. Is there a way to remove some of these by chance? Thanks!
