Audio cuts out and loses sync at various parts of file until pause/resume or seek

[AsheAshe 8]

I'm currently watching Nosferatu and have noticed at some points the audio cuts out for approx 1 second, it then resumes but the audio is then out of sync until you seek or pause/resume. 

I've uploaded a quick video showing this happening here: 

 

I deleted the file and downloaded another version, and that did the same at the exact same parts. I deleted that and tried 3 more. Exactly the same in each one at the same parts?

only appears when using the trueHD 7.1 audio track, if I select the DTS-HD 5.1 it does not trigger. 

am running emby server 4.9.1.90 ran in a container and am playing on an nvidia shield, have tried using the android and android TV app and same behaviour on each

Hi, we'll take a look at it. Thanks.

To add to this, I use a led light sync box by fancyleds. I've read today that the device doesn't do truehd pass through, so thought that might have been causing problems somehow but I've just tried it bypassing the box and straight from avr to tv and get the same behaviour. 
 

weird that it is happening at the same parts in multiple different downloads? Let me know if any other logs needed etc

OK we are looking at it. Thanks.

Hello, just checking in to see if any suggestions around this?

Yes and only with truehd track. But it happens at the same point in every copy I download. for example in Nosferatu extended UHD rip i am up to 01:11:18 and every copy cuts out here. 
 

I wonder if it is related to what is being discussed here

This references a fix that Kodi has apparently made:

yer this suggests it's shield software related

Yes the more I read about this the more it makes sense with the time stamps. It's essentially where there is a uhd release with theatrical cut and directors cut on same disc so two Audio cuts and it's where the audio merges. It happens to a select group of media but it will happen at specific points where the audio does merge 

 

seems like it requires development at shield level, and Kodi is unaffected because they use a different media player than emby & plex

might be the only solution is to use Kodi for just files that exhibit this behaviour

Again, non trueHD tracks will work fine on these as well as rips where it's not from a branched audio uhd release but probably won't know until it happens
