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!

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?

This is happening across all of the live streaming apps. Please investigate the root cause. This is absolutely repeatable. This makes it difficult to recommend Apple TV as a streaming device for anything but prerecorded material. I am available to assist in any troubleshooting.

Apps are engineered for the devices where they're downloaded, so you may have different settings or performance for each. For example, the Netflix app may work differently when downloaded directly on your Smart TV than it does when downloaded on your Apple TV, or it may require various settings to be customized to optimize performance through that device.

Watching ESPN last night during the baseball game the sync was so off the on camera was unwatchable. I have a high speed cable and running sound via hdmi . Watching Amazon prime or Netflix no problem but streaming ESPN was horrible.

I have the same issue but only if I use airplay to direct the audio to my speakers. However, if the audio is transmitted through bluetooth, then I get perfect synchrony. This problem only happened after my Apple tv HD had it last update on September 20, 2021.

To get very specific, shows like Star Trek DS9 (Netflix) and John Oliver (HBO) go out is sync almost immediately. Any live streaming app also. Newer shows and movies go out of sync less frequently. I have no problems with streaming directly through the TV (LG CX). I think this is my last apple TV.

Whenever I play Dolby Atmos content, there is a delay in audio playback in relation to the video. Dialog is slightly out of sync from lips. Explosions are heard slightly after you seem them. The delay is about 1/6 of a second.

I play with the AV delay of both the TV and the soundbar and was not able to sync the audio and video. The lowest setting on the AV sync is the closest I can get the audio to the video. Increasing the setting makes it worse.

Additionally, I also tested the Samsung TV's native Netflix app since it is the only one that outputs Atmos through the eARC. No sync issues with the TV's native Netflix app when playing Atmos content.

Are people still having A/V sync issues with their ATV box? I'm going from ATV>Receiver>TV. For me the video lags behind audio in some apps, not all, and to varying amounts if I have "Match Framerate" turned on. Turning it off fixed all syncing issues, but now all the apps feed content to the TV at 60fps instead of matching 24p material correctly. Match Framerate was one of the main reasons I bought this thing, and it's the only advantage this device has over the Nvidia Shield as an ultimate home theater streaming device. What's the point if I can't even use this feature??

I have the same problem with a Philips TV (65OLED907) with a built-in soundbar. Apple TV4K (latest version) has sync issues in all streaming apps (Apple TV+ is actually worst). I noticed a big improvement with tvOS 17.1 where a few episodes and films (Netflix and Prime) played without sync issues. This was not consistent, however, and most content and other apps are unusable with Atmos due to syncing. Native apps on the TV play Atmos without sync issues of course. Using the shortest possible and most expensive HDMI-cable (8K etc.) cable I could find.

I am having the same issue with syncing on Atmos content. Switch the Apple TV to 5.1 and no issues. I have tried so many combinations of settings, switched out all HDMI cables with brand new ones, reset to factory defaults all components and nothing. LG TV native apps with Atmos work flawlessly including the Apple TV+ app. Apple TV box is a no go on Atmos content. It is killing me. Any resolution for anyone yet? I signed up for beta in hopes that a beta update on tvOS might fix this. I was considering a new TV thinking that was the issue. Does eArc help?

That's all well and good, but one of the main reasons I bought this device was because of the framerate matching to run a pure clean 24fps signal to my TV. Bypassing it defeats the purpose of using this over another streaming device like the NV Shield Pro (which has better audio format compatibility anyway). This needs to be fixed or at least give us a manual AV signal delay control slider so we can sync it up ourselves without relying on having to own an iPhone to automagically do it (and still have it be wrong!)

Originally, I had "purple screen - HDCP erros" between the Roku Ultra and an expensive LG OLED TV that required disconnecting HDMI cables, swapping them, the ports I used, and powering off equipment - until I gave up and called for a replacement "Ultra" STB. Roku relectantly replaced it - only to have the same problems (which I suspect they know about). I eventualy gave up on the Ultra insisting that I get my exercise every night doing this nonsense and decided that a 4K Streaming Stick would eliminate the need for multiple HDMI cables that Roku Support suggested I change out.

The stick solved the HDCP issues; however the Audio Sync issues became the concern - and has been / still is present on EACH and EVERY Roku streamer / device / TV. Roku Support plays the same response to everyone: "What is the model, serial number, blah, blah, blah.." I haven't seen anyone say their problem has been fixed - instead, they just stop posting and complaining because they've come to realize that Roku doesnt have a permanent, workable fix! News flash - these same problems exist for Chromcast and Fire TV too.

Roku Support strings evetyone along by suggesting there is a fix - but they need 'more information" (a.k.a. time) to have their engineers look at YOUR problem (it is unique - no one else is having your problem!). They do this until the warranty return window for the streamer / device / TV has closed. Roku has been doing this for YEARS and it has likely become part of its mission statement. Its frustrating but it is what it is.

If my sync problem can't be fixed, using HDMI eARC, I'm sending back my new ROKU TV that not a week old. I'm not going threw these 4 steps every time I change a channel or switch from TV to streaming. This is BS.

I am experiencing the audio delay issue with my new Roku TV 50R4A5R/50R4AX. I am hearing impaired and using a Phonak TV streamer connected via optical port and the sound coming from the TV speakers is out of sync with the sound from the streamer. I'll be returning the TV and trying one with a different OS.

If you're in the middle of watching something and want to fix an Apple TV audio sync issue quickly but only temporarily, tap the back button on your Apple TV remote to return to the app you are streaming, then open and play your movie/TV show/video again. 9/10 times this will fix the issue for at least the next hour or so. If it doesn't fix it or if starts happening again, follow the steps below for a long-term solution. For more Apple TV tips, don't forget to sign up for our free Tip of the Day newsletter.

Have you ever started watching your Apple TV, then after a while, the audio is no longer synced to the video? This is more common than you think. If you experience your Hulu audio out of sync (or another streaming app), there are a few surefire ways to fix it:

That's it! The steps above will resolve most audio syncing problems. However, if you keep experiencing out-of-sync audio, check your TV, Apple TV, HDMI, and speaker cables for any visible damage and replace them if necessary. As a final measure, reach out directly to the official Apple Support team.

We hope that once you follow the steps above, you will never experience Netflix sound delays, YouTube TV sound out of sync, HBO Max audio out of sync, or any audio and video out-of-sync Apple TV issues ever again! Next, learn how to Chromecast from your iPhone.

@tnamouz @AnkerSupport I am experiencing the same issue as the posters above. I received my SoundBuds yesterday and they work flawlessly on my phone (Samsung s9) for music, gaming and video. I tried them today with my MacBook Pro and noticed that the sound was about 2 seconds ahead of the video playback in Youtube. I tried deleting the Bluetooth profile, resetting the headphones and refreshing the page a number of times but I continue to have the sync issue. The work-arounds listed above have not worked for me. I have other Bluetooth headsets that have worked fine with my MacBook. Is there a fix for this issue yet or should I reach out for a replacement pair?
