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 didn't know about this until it was too late to return the device. I don't think apple has it on its radar. At some point Apple could acknowledge the problem. I have two problems with audio on my apple tv. It doesn't work with my samsung tv and this is a widely known problem and then when sound does work its out of sync. Just a shame. I revert to my roku a lot when I can't stand the sound being so far off the video.

I think it’s with certain hardware combinations and they are aware but it’s not worth their time to fix. It won’t effect them as much as someone mentioned earlier. Most people aren't having issues at all. They have no incentive to help us here.


I have tried multiple factory resets and I’m using HomePods so my sound bar isn’t even in the mix here. Someone mentioned it isn’t exclusive to LG….I don’t think it is. I think it’s exclusive to certain hardware specs that all the effecting tvs seems to have in common. Some Samsungs and even some Sonys. But let’s be honest here, the majority of people in here have an LG tv with Dolby

I’m an Apple lover across the board and have been an avid techie my entire life, unfortunately there is something weird going on with my Apple TV 4K Netflix and HBO, exactly as you have stated. I have tried everything and beyond but cannot resolve the voice sync issue…with my vast experience, it is my opinion that only Apple can possibly solve this by being dedicated to this in a formal manner.


there are some temporary fixes here and there but within minutes or so the voice starts lagging again.


Apple, we all love you and embrace our lives with your superior products, please can you dedicate an in-house team to solve this problem as it’s not enjoyable at all to watch Netflix or HBO.


Peace🙏
