Dolby Atmos sync issue with Apple TV

I might have a solution. Under video and audio settings on my Apple TV I had the Match Content on. Sync problems.

Turned it off. Perfect audio sync through my homepod with Dolby Atmos still on.

Same issue here. For me the solution is to not use the appletv and run the appletv/hbo/netflix app on the tv instead. Then all is in sync and I can use Dolby Atmos!

It looks like appletv cannot deal with Dolby Atmos with some older model tv’s or is it an OS issue for Appletv?

Please Apple, fix this!

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??

Still having this same issue. Bypassing this and using tv based apps is not the solution. I am about to buy another Apple TV box to see if that is the issue. But clearly my Sonos and tv are fine if excluding the Apple TV box. Apple support wanted me to go through a rigmarole and send them a bunch of data. I have tried 5 different cables. Downgrading the Atv box to don’t 5.1 used to fix the problem. Now I’m having issues with syncing even on 5.1. It’s crazy. If it was app specific I would say maybe it’s the provider. But it’s all Apple TV apps.

has anyone been successful fixing it or is everyone like me. Get motivated to fix it. Try a bunch of stuff that doesn’t work. Then give up again when super frustration sets in. Then revisit it when you have calmed down after a few months. I’ve lost my marbles on numerous occasions.

i now have the system in stereo. Which seems to be ok. But my brother came over and still can see syncing issues. I’ve about had it with this setup. I can’t see how it’s not an Apple TV issue. How can you want to control the living room experience, Apple, when you can’t help us troubleshoot this. Asking me to check the cable again is not productive.

Same exact issue. Reset AV settings, and pulled the power on all devices in my chain for a couple minutes. No difference.

2.0 and 5.1 are fine. Atmos is several frames out of sync in all apps. Unwatchable.

Gear:

LG C9

Apple TV 4K (second gen on 17.1)

Sony STR-DN1080

ATV goes to TV, then eARC to AVR.

I had the same issue after my Apple TV 4K updated recently. It seems to be fixed after I went into my television audio settings and changed it from “Passthrough” to “Auto.” The auto setting left the sound very delayed, taking about 15 seconds to start playing after starting a video. Deciding this was not a good option, I changed it back ti “passthrough” and now everything is working fine.

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 have an Apple TV 4K tvOS 17.1.2 Sonos Arc Soundbar LG C8 OLED with ARC

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?

I’m sort of in the same boat as well. AppleTV 4K and a Samsung Frame TV with a Sonos Arc (and sub) setup. Netflix, Disney+ all work just fine but the Apple TV plus app has major sync issues. The only thing I’ve found that works is turning off the Atmos and going with only 5.1 on the Apple TV sound settings. Everything else was problematic. I’ve also used the native apps on the Samsung and no issues, so it definitely feels like an issue with the Apple TV at this point.

This broke again with the latest GA software. Go figure.

The good news is, I think it's related to eARC. I changed my topology so that the ATV was going directly to my AVR and the issue went away.

Previously I had been connecting to my LG C9 TV and using eARC to pass the audio back to my Sony STR-DN1080 AVR. Now with a direct connect to the AVR things are working fine. Whew.

Same issue. Atv connected direct to a Denon 6500w. Differing levels of sync issue. Setup to run Atmos 7.1.4

BBC iplayer almost perfect

AppleTV movie awful with video in front of audio

Prime - video just in front of audio

Netflix - video just in front of audio

All cables a highest quality, tried changing Atv video settings - no change.

Tried Atv connected to the TV, used eARC to push audio back to the Denon. No better.

issue has to be the Atv. Atv is running the latest iOS

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!)

What is “shortest”?

Still the same problem, tvOS 17.5.1 & latest version of Infuse Pro.

It is all ok after turning off the match frame.

Hope Apple can fix this issue ASAP!!!

I have the same problem ... and this is a recurring issue: it was present for some time after I bought the AppleTV4K over two years ago; then it was fixed but just recently audio has been going out of sync in Dolby Atmos again.

My ATV4K is connected to a Panasonic OLED (JZ2000) with built-in Dolby Atmos system. In the TV's native apps audio is synced, on the AppleTV there is a significant delay.

Disabling Atmos fixes the problem; no sync issues in 5.1
