Apple TV audio/video sync issues

Never an issue with my Apple TV until Fall of this year after the update. It doesn’t matter the 3rd party app. My audio quickly stutters and then starts to lose sync with the video. I’ve tried numerous apps, 3 different HDMI inputs and different cables…I’ve connected directly to Ethernet on 1Gig Internet and I’ve done everything Apple has recommended with ZERO resolve.

You can tell that it is an Apple issue because the audio is even out of sync within the platform of their own Apple TV app. When I scroll through their menu and click on different options for settings, the normal click sounds are delayed. They are passing the buck and lying that it’s 3rd party apps. My Apple TV is pretty much useless at this point and I’m learning to do without it by using my TV’s App Store apps that provide most all of what I need. It’s not as streamlined as Apple, but when Apple can’t get it right and points the finger elsewhere…maybe it’s time to just go elsewhere and stop being loyal to Apple.

Focusing on the type of ethernet cable is pointless. A cat5 cable will reliably carry 100 Mbps reliably. cat6 will carry 1Gbps and Cat7 is not IEEE recognized yet. How many people have more than 100Mbps internet today?

Internet bandwidth does not have to match the HDMI cable as video processing converts what comes in over the wire (Internet) into the best AppleTV can produce for the destination TV. HDMI 2.1 cable supports 18Gbps which, I think, can support up to 8K. How many of you are watching 8K when such content is not yet available?

The problem is very likely related to the Apple software (or underlying hardware) related to audio processing. Changes to the default configuration may be causing the loss of sync.

this is definitely an issue with latest version of Apple TV. Multi apps, YouTube in particular. Reboot fixes it for a couple of hours. Apple need to fix this!

A few weeks ago, I reset my audio settings on AppleTV and it has worked perfectly under all conditions since.

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.

Thank you.

Same problem. Have a Apple TVOS on version 15.0. connected to a projector. Have been playing the audio over a first generation airport express for years without any issues up until recently where it now lags across all apps. It stutters and gets out of sync almost immediately. Clearly a problem since the last update that needs to be fixed.

We’re having the same issues. Apple TV 4K via high speed HDMI to the TV. Then sound from the tv to the sound bar (not arc compatible) via optical cable.

the sound is calibrated using the Apple calibration and iPhone, but the sound eventually runs away from the video. No idea how to rectify it.

I could connect the Apple tv via the hdmi to the hdmi in on the soundbar then to the tv via the hdmi out, but not sure if I’d lose some video quality in the process.

When you are watching the app. Go to the menu and send feedback. Simple. Let’s hope they do something about it. I’m sure if enough people that take time to read these forums and or provide feedback in the app maybe they would fix it quicker…

Hey All,

Chiming in here. I have this same issue with an LG TV. I just purchased a brand new Apple TV 4k using UHS HDMI 2.1 cable I bought a year ago . I’m unclear if it is 48gbps but it’s labeled as ultra high speed. The problem seems to only happen with the history channel or A&E apps or anything on their network. I have tried all of the solutions listed here. Changing configurations on either the ATV or the LGTV have done nothing so far. My Apple TV is wired straight to my router. I am updated completely but do not have the Beta software installed. It doesn't seem to make a difference if I use airplay or play the audio from my sound bar which is wired via optical cable.

I see a lot of LG TVs in this thread. Could that be the culprit? Has anyone solved this?

All,

I agree with Jason, make sure your Apple TV is wired straight to my router. Cat 6 or better cables. It's a shame Apple doesn't allow us to set the Hardware settings for ethernet. Instead, it detects speeds base on detection from the ethernet cable, so use a quality cable. I use Cat 7 myself.

This has been happening to me too except also with TV+ and iTunes.

My issues are with hard wired speakers fed via hdmi and not on all streams. There is an option for sync in the settings for Bluetooth or Airplay .. wonder if that helps the airplay issues ?

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.
