I guess related, do you guys have an idea on if you can fix the Dolby Atmos dropouts on several Disney UHD movies or is it something Kodi need to fix?
As per the end of Playback improvements for 4K HEVC UHD content - #77 by sam_nazarko thread you can see that the issue has been resolved for PC playback but still exists on the Vero and shield etc.
I don’t know much detail apart from people saying the Disney movies sometimes have very high bitrate that causes the audio to drop. It is always at exactly the same places per movie. Guardians of the Galaxy 2 only has a few, but Pirates of the Caribbean Dead Man’s Chest and Coco has loads of drops.

audio
TrueHD bitstreaming can cause audio to cut out briefly on high bitrate Atmos str… eams (as found on UHD Blu-rays).
This is caused by the individual frames being too large for the current logic that builds the MAT frame for HDMI transmission. Unfortunately the exact workings of the MAT format are unknown.
A few examples where this happens:
> - “Pirates of the Caribbean - Dead Men Tell No Tales” - Max Bit rate is 11.9 Mb/s : eg drops out a couple of times between 17:45 and 19:00 minutes into the movie
> - “Guardians of the Galaxy Vol II” - Max Bit rate is 11.3 Mb/s: eg drops out at 1:09:24 where TaserFace gets killed is one example.
> - “Maze Runner: The Death Cure” - Max Bit rate is 12.1 Mb/s: eg Right at the beginning of the Main Title when the 20th Century clip is running. Drops outs so frequent that playback can actually stall.
