Thanks. I downloaded it as well as the version for the ATV 4K. How does one downgrade an ATV 4K? Since the file is available I'm assuming it's possible.Download tvOS 13.4.8 (17M61) for Apple TV 4 (2015) / IPSW Downloads

the build number is the same as the rc which I tried last week and reported issue still present as it is in 14.7 beta 1.
apple have said it will be fixed in a future update so my guess currently is 15.0!!
however the crackle affects iOS, iPadOS, tvOS & macOS so it could be a while.
I have also had massive issues with TVOS 14.5. After a ton of diagnosing it all came down to the Apple TV and 14.5.
I can stream from iTunes, music, my NAS All sources the sound slowly goes out of sync and I’ve got to click back 10 seconds to get it into sync.
I have wiped my Apple TV’s and reinstalled the OS with no Resolution.
The issue is definitely 14.5. Come on Apple figure this out and update the dam system

I still have no solution to this audio problem on the AppleTV HD and 4K and I see many others are also having the same issue as being reported here, https://discussions.apple.com/thread/252716640
Thanks goodness I have kept a few AppleTV 3's that I can use for now.

I've been having problems with audio sync and crackling in the sound since 14.5 with both a Apple TV HD box that got upgraded and a brand new Apple TV 4k out the box. I'm happy to say that the new 14.7 download seems to have fixed both these issues. (I've only downloaded 14.7 to the 4k box, I'm leaving the HD box at TVOS 13 for the time being.)
14.7 seems to have addressed the audio out of sync issue for me. I did not have the crackling issues others had. Working so far on ATV 4 and 4K ATV
What OS you using on your Mac? I still have issues with Monterey (using TV TVAPP) to ATV HD on anything above 13.8
Just installed 14.7 and I can verify that the audio sync issue has disappeared for me as well. Thank God it was irritating the pants off me
Big Sur 11.5 RC takes care of the crackle audio issue in Apple TV app.
Big Sur 11.4 does not.
With my ATV 4K running 14.7 I am finding the lip-sync problem with stereo Homepods has returned for some apps. I thought I would troubleshoot by adjusting the ATV audio settings (change from Auto to Stereo) but found that this setting was now grayed out.
I guess I have to wait for tvOS and TV app updates to fix the irritating problem.

Nope. It is better, way less movies I stream through the Computers app have the issue but a lot still do that were just fine before...
I have recently bought a Apple TV 4K and it’s running on tvOS 15.
When I watch any film with Atmos sound and Dolby Vision picture after 10-15 mins the audio starts to get more and more delayed. If I exit and go back in and rewind, it goes back in sync but again after 15 mins is behind and out of sync again.
I am not using a sound bar, just a high speed 2.0a HDMI plugged into my TV and sound coming from TV speakers. My tv is a 12/58PUS7505 Philips 4K TV with Dolby Vision and Atmos. It runs at 60hz but I tried changing the Apple TV settings to 50hz and I have turned match frame rate off but the problem persists. My TV can play Atmos and Vision from its own Netflix app and from Sky Q with no issues so it’s not the TV.
Also the sound crackles when I play Atmos after playing non Atmos and sometimes unplugging and re plugging the HDMI works, sometimes it doesn’t and sometimes videos and songs will stop start automatically and will only stop if I reset the box.
I have factory reset the box, tried different ports and cables, tried AirPlay all with no luck.
