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

Apple Support told me to check if problem also exists with paired BT speakers (KEF MUO used) to exclude problems on signal path.
Unfortunately it does ...
Also I should check if problem with same media exists on iPhone (iPhone 11 iOS 14.4.2 used) and there is no problem. Audio is fine.
But! I updated to 14.5.1 and now I have this problem also on my iPhone (just like mark-s1)!
Dolby_Digital_sample.m4v: Audio is fine.
DTS_sample.m4v: Crackling/popping noise in audio.
Unfortunately Duration_LastFrame doesn't have anything to do with this problem. As you can see Dolby_Digital_sample.m4v doesn't have this flag.
Please Apple, fix this soon.

Oh man, that's pretty bad ...
I also made a support call and opened a ticket.
This thread is linked in this ticket.
If they cannot/don't want to solve this problem I think the only solution is to buy an Apple TV 4K (with tvOS < 14.5) on the used market.
that would assume you can locate one. I have an Apple TV HD which is running tvOS 14.4 and every time it is woken up it prompts to do a software update. And I'm sure someone will click on update when waking up the 4K one if I buy one as that would be in the lounge. plus I currently have 2 4K models so to be able to access my library could be expensive. As much as I don't want to I might have to see if Plex has audio issues.
Here are the specifications for the Apple TV 4K 5th gen:
https://www.apple.com/shop/product/FP7P2LL/A/Refurbished-Apple-TV-4K-64GB
Audio
HE-AAC (V1), AAC (up to 320 Kbps), protected AAC (from iTunes Store), MP3 (up to 320 Kbps), MP3 VBR, Apple Lossless, FLAC, AIFF, and WAV; AC-3 (Dolby Digital 5.1) and E-AC-3 (Dolby Digital Plus 7.1 surround sound)
Because we're using the supported Apple Lossless Audio Codec from specs Apple should definitely fix this problem!
Oh okay, that's bad.
I'll update to 13.4.8 later and hope for a fix.
I just want to confirm that everything works now. No crackling/popping sound and asynchronous anymore.
BTW: I always had to open the channels (from 2.0 to 5.1) by opening a TV streaming app when watching movies from home share.
But with this version I don't need to.
I hope you can find a way to select which tvOS by default the auto update will select the newest which will be 14.5
Only the HD one with the USB C port you can definitely choose as you are able to restore the ispw via iTunes or finder.
Just found this thread - I'm having the same issue playing content via home sharing from a Mac Pro hard-wired within my network to Apple TV. I have an Apple TV 4k and this is pretty frustrating. Audio slowly gets more and more out of sync until it's completely gone. Does the newest Apple TV fix this?
i have now been asked to upload a copy of an affected file for the software team to look at.
Already did that on Wednesday and they were able to comprehend the problem.
So I think that's good news.
(Case Number: 101379274997)
I have an appointment at the genius bar on Friday.
Hopefully they will be able to resolve the issues we are facing soon then.
What devices have they requested you take to the Genius Bar?
My Apple TV 4K.
I'm glad they repalced it.
Unfortunately it's coming with tvOS 12.4.
I'm currently figuring out how to update to 14.4 ...
unfortunately none of the latest updates are seeming to resolve the crackle issue
so there is some good news coming if today’s dp is anything to go on! 😉
Ok, I’ll admit to being slow on the uptake!!
what’s the good news… and the dp?!
Same exact problem over here - files play fine on OSX, sound crackling on 14.5, and iPhone iOS 14.5.
Crackling/popping noise in movies since tvOS 14.5
