Changing buffer settings can resync audio and video.
Open the Plex app > go to Preferences > click Player > and Change Buffer Settings from auto to:
- Initial buffer: 25mb.
- Pending Buffer: 50mb.
- Total buffer: 75mb. Or use other buffer sizes to maintain sync in higher bitrate videos.

Some devices like NVIDIA Shield Android TV provide an option to adjust the audio delay. This is how to adjust the audio video sync on SHIELD:

- Choose Display & Sound.

- Using the slider, match the bouncing ball to the sound.
Go back to the streaming video on Plex and see if audio video sync is now okay. Try this method for other streaming devices too.
