Apple TV audio/video sync issues

Lately I’ve been having difficulty with lagging audio to video syncing with my Apple TV 4K. If I restart it, the problem is temporarily fixed, but after about 5 minutes of watching Netflix or hbo now, the audio will start lagging. This doesn’t typically occur with Disney plus or streaming movies from iTunes. Once the audio starts to lag with the service, it continues to lag once I exit the app. The sounds you hear when hovering over different apps lags significantly. Again, this is only fixed by resetting the Apple TV. I have run Netflix through my (smart) TV and had no problems with audio (it’s the same TV I have the Apple TV connected to). I’ve also ensured my internet connection/speed is good (>300Mbs), and have tried connecting my Apple TV to my router via Ethernet cable, with no improvement. This problem has been present for months but has gotten significantly worse recently. Changing between audio formats doesn’t do anything (a suggestion I saw when researching the topic). Please help.

I just updated my Apple TV 4K and this same thing started happening to me today. Watched two Netfix movies last night with no issues, but tonight the sound streams to my airplay Bose speakers ahead of the video. Also, my picture is slightly glitchy. When I change to TV speaker (which runs through HDMI cable) sound is perfectly synced with video and no more glitch. Again, this was NOT an issue until my Apple TV updated. This doesn't look like a fluke. It looks like a BAD UPGRADE. PLEASE FIX ASAP!

Yes it’s ridiculous. Hey Apple - take your head out of your asses and fix this. This is like first gen Fire Stick ****. Embarrassing.

I’m glad you got it solved. But I don’t have Sony anything. Just a sound bar. It turns out it’s just a single movie that is doing this to me, so maybe its file is corrupted server side.

Strangely enough (or by design?) the content that was out of sync (video / audio) is now fixed for me after tvOS 15.1.

Got mine fixed… it was an issue with the audio and sound mode on my TV. Once I changed it, it lined up. It’s like the TV firmware updated and the options I had picked weren’t available anymore.

I purchased 2 Ultra High Speed HDMI cables (one for AppleTV to TV and one for my Sonos to my TV ARC). It seems to have remedied all audio issues.

Found something interesting,

if when I do the audio sync calibration, I hold the phone on my sitting position instead of putting it close to the tv, the sync is almost perfect.

If your TV is in the loop for the audio, which it most likely is, try adjusting the audio and picture modes on your TV. That fixed mine and was the best discovery ever!

Total waste of money. Can’t watch anything without wanting to throw it through the window.

I’ll be leaving my thoughts on this on every forum I can find

I turned off Dolby Atmos and switched to 5.1, which seems to have worked.

Nov 14, 2021 11:57 PM in response to Martincape

I have issues with just hdmi and tv speakers.

Thanks! That worked for me on the 2021 NY City Macy’s Day Parade!!

I have a very simple Vizio sound bar and same issue regardless of audio format or even if I just use my tv’s built in speakers.

Any advice or suggestions?

Please Apple, give us a mechanism to revert to iOS 14! This sync issue / audio dropping is making my Apple TV useless. Fix the buffering it's no longer buffering!
