Two issues are currently known, which causes playback of videos through the Samsung smart TV PLEX app to have offset between sound and image, leading to audio out of sync:
- Very small but gradually increasing offset during playback, which can be temporarily fixed by pausing and resuming the video.
- Significant offset which remains the same through the entire video, with no change from using the method mentioned below.
How to fix it
To fix this sync problem between video and audio in the PLEX app, follow these steps:
- On your TV, open the PLEX app and navigate to:
Preferences -> Player
- Change the three buffer settings from “auto” to:
Initial Buffer: 25MB
Pending Buffer: 50MB
Total Buffer: 75MB
This seems to fix the issue of PLEX audio being out of sync!
Maybe you will have to use other buffer sizes for maintaining sync in higher bitrate videos.
Also, maybe this audio out of sync issue may have been fixed in newer PLEX app versions.
I hope that this could also prove to be a fix for the issue with gradually shifting sound which is normally solved by pausing and resuming playback to resync.
Enjoy, and share if you found this post useful =)
I hope it helps.
I’m currently using 2.007 Plex on SmartHub for 2012 plasma TV Samsung
Thank you, this was a very annoying issue for me for a long time!
Perfect! Do you have a solution for stuttering?
Drop the resolution down.
This worked like a charm, this issue had been bugging me for ages. Thank you.
Worked on the ubd-k8500 4K Samsung bluray player like a charm. Cheers!
Thanks man! It worked nice for me!
I’m in preferences but there is no player option???
Thanks for the tip, this made the plex app usable and now I can finally watch my movies without lip sync issues on my Samsung f6500 46″ 🙂
