I’ll take this opportunity to remind folks that Plex did address this issue by adding a set-once-and-forget (at least in my experience) manual audio offset adjustment to mitigate it. I know it’s not the permanent, no-effort-required fix that is desired, but it is a viable workaround for this specific issue for those willing to employ it. It requires some effort to be sure, but if you’re sensitive enough to see the sync problem then you’re likely sensitive enough to see the adjustment work.
I mention this only as a reminder that this problem has not been completely ignored.
You are lucky that this solution works for you. For other users the amount of the offset is not fixed to one single value you can set and forget. In my case I would say that actually around 50% of my library plays with no sync problems, the rest has sync problems all around the place.
Just after my last post here I realised that the offset was actually available to all users, the reason I hadn’t seen the option yet was because I was still on the old player.
I enabled the enhanced player, removed the offset from my sound bar, spent some time calibrating the Plex sync (landed on +400), and went through and recalibrated Bluetooth audio sync for all the formats (painful). Also happy to report it does the job, and I have audio sync for Plex and every other app when playing back through sound bar and Bluetooth headphones.
There was a point where the sync issue reappeared and my heart dropped, but a post on here pointed out that Plex was reverting to the old player to play a specific Dolby Vision profile. It’s fairly simple for me to check for and avoid that profile in the future.
Not the most ideal solution, but aside from the DV profile issue I haven’t thought about audio sync since I set it all up, which is a big improvement.
I really feel for the users who are having sync issues that vary across all different files, hopefully something is worked out soon to fix it. I’m beginning to get the feeling there are 2 or 3 separate issues that are being conflated into 1 in this thread and causing confusion.
No. The Plex team have officially stated they are not actively working on this issue. In fact, they even stated that, from all the current plans and scheduled future workloads, this issue is not included to be addressed. Yes. Really. They stated that.
This issue is not on any timeline to be addressed whatsoever. But they are open to think about maybe adding this issue to the timeline at some time in the future.
I’ve been using Infuse since 2015. It has always been a better video player than Plex. However, I really like Plex’s UI and feature set, so it pains me a bit to see Plex turn their backs on this issue.
I’ll keep using Infuse but I would really like to see this issue fixed someday. Until then, I will hope Infuse brings profiles and some other Plex features over.
Plex ATV development seems to be pretty much at a standstill, whereas Infuse development marches on at pace - and the dev even finds time to be very active in the community forum.
I’m sure the gap between Infuse feature set and Plex will continue to close, but I echo your feelings, I’d prefer to use Plex!
I stopped using Plex about a year ago when the audio sync issues started and it became clear it was not going to be resolved soon, and moved to Infuse. I just tried Plex today as I was considering buying a lifetime pass in the black Friday sale and was shocked to see this still hasn’t been fixed.
Actor’s mouths moving in time with the audio seems pretty fundamental to a media platform, and while most won’t post on here, Plex must be losing paying customers hand over fist. Lets hope it will work it’s way to the top of the priorities. All the best for another year, Steve
Not sure if this will be helpful to all or already mentioned and buried in the thread. I was having audio sync and frame drop with 4k HDR content, and found an article using Bing AI chat (of all things) that pointed to enabling the following settings in Apple TV settings: Settings → Video and Audio → Match Content: Match Dynamic Range : Set to On Match Frame Rate: Set to On
(by default, both of these were off)
Apple TV 4K (new), tvOS 17.1 (21K69)
With these enabled, my experience has been flawless all day, hope this helps others if it applies to them! Be glad to share any other details if it would be helpful. Have Plex Video Quality settings to:
Auto Adjust Quality: Off
Home Streaming: Maximum
Internet Streaming: Maximum
Play Smaller Videos at Original Quality: On
But with the settings that you have listed the important part is whether you are using the old or new audio engine and that’s by a country mile the most important setting, possibly followed by the video engine setting.
It’s not really about the default Apple TV settings that will solve this because they won’t. I set up the 4th Apple TV in my house yesterday and everything that you mention is OFF by default is actually ON by default?
Maybe a geo-location thing or you changed your settings in the past and simply forgot ?
The bottom line is… are you using the new audio engine (that actually is ALWAYS on by default?)
good luck, the internal communication is so bad, their billing department blamed this issue on Apple and refused my refund request lol This was after plex devs admitted it was their own fault.
