Dolby TrueHD Atmos sound track issue in same rare occasion

[Frage]

Hi everyone,

I'm using Docker Jellyfin Server (last version up to this day) on my UGreen NAS to playback my 4K Remux.

To play my movies I'm using my CoreELEC device (AM6Bp) with the Kodi plugin. AV10 / AMP10 Audio, playback devices directly to my AV10 (no eARC), 5.1 speakers.

So far everything is working perfectly ! But I have one issue that happen rarely in some of my remux. In my last 20 movies, 3 of them got audio glitches. All 3 are Dolby Atmos audio.

When I playback the Dolby TrueHD Atmos Sound track I have 0.5sec of audio drop. If I go back and player again, same issue, it is on fixed timecode.

At first I was thinking that a player issue. I tried to play the same file on my Nvidia Shield using the native Jellyfin App and same issue at the same timecode.

Then I thought that was a file issue so I played from my PC the MKV with VLC and I don't experience any issue.

Back to my Shield TV and CoreELEC, I don't have any issue if I select the AC3 (compatibility track).

I tried to reset my Marantz AV10 / AMP10, still having the issue. I tried the Pure mode which is no audio processing -> still having the issue.

So my last guess is a Jellyfin issue ? To be honest I'm running out of ideas, any help is appreciated.

Here a clip to show you the issue :

Here my CoreELEC logs even tho I don't think this is useful :

It seems I have logs about the error and it is throwing a python error, if someone is aware of this :
