@sergiou87 Could you update us on the status, please? Lots of paying customers in this thread, the problem clearly exists. If you need more info, let’s troubleshoot. If you have identified the problem and it’s on your roadmap, that’s useful information too. Or are we all just waiting for nothing?

Yep the same issue here. Infuse works flawlessly but the Plex app is dreadful with audio on 4k content. I really don’t want to move to Infuse as it’s interface is so bad in comparison to the official Plex app, such a massive shame that such a huge issue is still so prevalent literally years after it’s been reported.

MrMC works also great with Plex and has more of a Plex-like interface than Infuse (and is only a one-time purchase), as it is based on Kodi. But I hope this issue gets fixed soon. Now the Plex-app is just idlingin on my Apple TV.
Can’t direct play certain codecs without enhanced player. Can’t airplay audio to HomePods with enhanced player.
Infuse works for both but I’d prefer to use the Plex client. This seems to be a problem for a long time now. 
I’ve had “Audio Sync” issues with the Enhanced and old player for a while. Disabling the enhanced player now resolved the sync issue as of a month ago.
All content is:
- 1080P SDR
- Majority of my content is 24 FPS
- 5.1 audio (AAC, EAC3)
- Match frame rate “On”
Playing the same titles on my 2018 LG WebOS TV does not induce the Audio sync issue (no enhanced player).
I believe the enhanced player was working prior to public release… but that was a while ago.
As a lifetime Plex Pass member, I hope this gets resolved.
Unfortunately, no updates about this 
None of the devs in the team can reproduce this problem, so it’s a bit hard to even guess where the problem might be. With the help of some users we tried to pinpoint the problem to specific codecs, hardware, etc. but we haven’t seen a pattern, seems kind of random.
In any case this problem is in our radar, but not explicitly in our roadmap. There is something we’d like to try around audio playback that might help with this issue, but of course we can’t confirm that by ourselves and we’ll need some affected users to test it 
I volunteer, just tell me what you need.
Thank you, but first we need to actually implement that thing we want to try. Unfortunately is not super trivial
I’m using an Apple TV 4K. I use ‘Match content’ and ‘Match framerate’ and always have this problem. It doesn’t matter if I start from 50hz or 60hz, SDR or HDR. It also doesn’t matter wat codec I use (mainly AVC & HEVC) or what audio codec (mainly AAC, DD, DD+ & DTS), the audio is always out of sync. Audio output via HDMI. No difference in multi-channel or stereo audio. Using direct play.
This is only an issue with the enhanched player (which I need for direct playback). When playing Plex movies with Infuse or MrMC the problem is not there, so it seems not a problem in the HDMI chain.
Based on this I would have expected it to be much easier to reproduce. The problem is also still there on the new tvOS 14.

I also have this issue although it’s a bit weird, last week we watched a movie on Plex (Plex Server is running on a Mac mini) on my Apple TV 4K and it worked flawlessly. This week we tried playing the same movie and the audio was out of sync. Nothing has changed other than updating to tvOS 14… but this issue was already present with other movies since before updating tvOS.
I had Frame Rate Matching set to off while I had audio sync issues, after enabling it it is now in sync.
Also having this same issue for months now. I can provide whatever logs you need. And I know this is a plex only issue, because content plays fine elsewhere and in other apps.
I will be willing to provide whatever logs you require to fix this. I cannot believe that this is completely unproduceable, with enough people posting about it.
But I highly doubt it is an environmental issue and rather a problem with Plex.
This is not strictly on topic but I just found out Amazon Prime Video has the same audio delay issue, also connected to Match Framerate enabled. That is the only other app I’ve seen it in though. Related link: Amazon Digital and Device Forums - US
Would it be possible to add an “audio delay” option for the app?
In Kodi for example it is possible to set an audio delay in milliseconds steps, e.g. “+125ms”.
This would allow to synchronise the audio for all situations.
Please add this option. Else I cannot use your app.
Thanks in advance!

Just adding to this thread that I am also seeing issue now with the PLEX Apple TV App. I just updated to a new TV with HDR support and the audio sync issues are maddening, I’ve had to switch over to the TVs Roku PLEX app which works just fine playing HDR10 content. I tried playing the same content that I recently played on my old TV (non-HDR TV no audio sync issues) and it seems the issue is because its playing HDR10 content on the new TV. Ideally I’d like to keep using the Apple TV… let us know if there are any updates on getting this fixed.
@Plex Devs
The MPV Player already has that option. Maybe that makes it easier to implement?
As far as I know the Plex client also uses MPV as a basis?
I’ve done some more testing, I am starting to believe it has to do with the “Match Frame Rate” setting on the ATV playing HDR / DV content. I noticed the issue again today on both Netflix and a ATV+ show, when I disabled “Match Frame Rate” it removed the audio sync issue. But having the ATV output 24fps content as 60fps isn’t ideal…
You could’ve saved some time for yourself and just read the more recent posts to come to the same conclusion. Anyhow, good to have one more confirmation. For now I’m using the old video player as a workaround but it’s not ideal as I have lots of different media and am fairly dependent on transcoding.
After some testing with tvOS 14.2 tonight the audio sync issues seem to be resolved for me. Hopefully that’s the end of it and we can use Match Frame Rate now.
I eagerly updated today and… there was a change indeed. Not the one I wanted though. Now the old player is broken too! Leaving my only option to turn off frame rate matching, which I obviously don’t want to do. To everyone using old player as a workaround, update at your own risk!
At least we’re starting to see reports on apps other than Plex so it might actually be an Apple TV thing, or a combination of the two.
Just to tag along here, I’m seeing the same issues, 4K HDR content with about half a second of audio lag. In our case, content matching is disabled. Infuse works, but there’s screen juttering/tearing.
