I have 2 Intel NUCs running LE 10.0.4 and they play all my .m2ts video files containing DTS-HD Master Audio correctly. Their Audio Streams are identified as: English - DTS-HD MA 5.1 (side) - 6 channels [default] (1/1). My AVR correctly identifies them as DTS-HD Master Audio
If I update to 10.95.0 (Nexus), the Audio Streams are identified as: English - DTS 0 channels - 0 channels (1/1). My AVR plays them as plain DTS - not DTS-HD Master Audio
Same problem running Kodi Nexus on a Windows 10 computer.
I converted one of the .m2ts files to .mkv and it plays DTS-HD Master Audio correctly.
Can anyone else confirm this?
Here's a link to a sample .m2ts video file that contains DTS-HD Master Audio:
Samples - Official Kodi Wiki
Scroll down to HD / object-based Audio Test Clips and select number 14 to download.
It will play properly with LE 10.0.4 (Matrix) but not with LE 10.95.0 (Nexus). The AVR should display "DTS-HD Master Audio"
I reported the bug to Kodi Github
I am surprised that no one else has recognized this problem. I submitted this issue to Github a month ago and not one reply. A Libreelec developer has confirmed this problem and asked me to post it here and also on the Github page.
Kodi is in large parts unmaintained with volunteers missing to step in. Therefore: No other choice than waiting.
If you want to try something:
https://github.com/xbmc/xbmc/blob/master...g.cpp#L529 <- go here and make the if condition fail, e.g. if (false &&
and see if that fixes the issue. This is a livetv hack for fast switching ... which from time to time hits your file formats as well.

Thanks for the reply. It looks like I will have to wait then.
I don't understand what you want me to try in the above post.

Thanks for catching this. I'll hold off upgrading my Intel NUC to LE11 until this is resolved. I have a mix of M2TS and MKV files.

^ This fixed it for me. I don't see any downsides, live tv switching speed looks the same.
Sorry - but that's all Greek to me. I have no idea what fixed what. I know nothing about Linux or coding. Please explain in much simpler terms.
DTS-HD MA tracks would be properly detected if Kodi is compiled with that patch.

Will .m2ts files containing DTS-HD MA tracks work properly? If so, who will compile using that patch? I know nothing about compiling.
By the way, thanks for all your help. At least it's getting some attention now.

Yes.

I suppose you will have to wait..

That worked!
What about updates? Will this patch be included? And how about a version for Windows?
Thanks
