Crackling/popping noise in movies since tvOS 14.5

Hello,


since I updated my Apple TV 4K (5th gen.) from tvOS 14.4 to 14.5 yesterday I hear crackling/popping noise in movies.


I can only hear this in movies.

Music, audiobooks and TV streaming via app are not affected.


Here is a sample of the problem (Spider-Man: Homecoming 5:38): https://streamable.com/2to2a9


Please guys help me to fix this.

I cannot watch my movies since yesterday, this is not really well ...


Best

Felix

Great. Keep us up to date.


I did some research.


I have hundreds of BluRays copied to m4v and converted containing audio streams to Apple Lossless Audio Codec to keep quality.

So audio streams of all movies have the ALAC but the problem occurs only with audio streams whose original source is DTS!

Dolby sources don't have this problem.


See additional text:


The only difference is this:

Duration_LastFrame                       : -47 ms


My conclusion ist that all audio streams lacking Duration_LastFrame have this problem!
