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’ve had an intermittent audio video synch issue with my Apple TV 4K and my LG OLED TV. The issue seems to happen across many different apps and only on the 4K version of the Apple TV. Apple checked into it and said to check with LG. I called LG and was told it is a known issue. The solution they recommended was to turn off the Dolby Atmos and smart sound settings on the LG OLED T V.

I have the same issues on almost all my streaming apps recently. Hasn’t been a problem in the past. I’d say the issue started about 2 months ago. Restarting Apple TV fixes the issue temporarily. This thread leaves me to believe it’s not just my tv. I have an LG CX model and work in the AV industry. I’m hesitating recommending this to my clients as I will be dealing with service calls all the time.

I am having the same issues with the NEW Apple TV. lagging after watching for a few minutes, however, may lagging occurs on YouTube TV and other apps. I have been a big supporter of Apple TV but if this lagging is not corrected I will have to change hardware, which is a lot since I have two homes. What is Apple doing to try and fix this problem?

Agreed!- Roku or Fire?


Very disappointed with my new Macbook Air (2020 - intel chip) also. Got 16gb and highest rated processor and it under-performs my old 2012 Macbook Air. My old Apple TV was much more reliable also.


How are System76/Ubuntu laptops performing these days? I may even jump back over to a Windows system. Heck, I can buy a Windows laptop and a tablet PC for the price of my Air...Hmmm


Sorry to see this. I really liked my 6 other Apple computers. I guess all good things come to an end.

I have the exact same issue today is October 10, 2021. It’s been like this for about two weeks. I don’t even like watching it. If this keeps happening I’m going to switch to a more reliable device. I hope apple does something soon. I’ve never had issues like this before two weeks ago. I’m glad my tv has most of the same apps I use on Apple TV. Although some are not available. I hope a fix is found.

I absolutely experience something similar with my Apple TV 4K. When watching some shows on some apps (being vague as it seems not specific to just one) after 2-3 minutes the audio with repeat about 4 seconds, but the video continues play as normal, resulting in a 4 second sync issue. I have updated os, tried auto and specific video and audio settings without eliminating the problem. I expect this to be reported as a repeatable and diverse user issue.

Thank you.
