Audio Sync issues with Chromecast Ultra.

I have been having audio sync issues for a few weeks now using Plex. It only happens when casting to my Chromecast if I view the video on Plex using my phone or on my pc there are no issues. I have also cast the same video file to my Chromecast using VideoStream and it works fine. Is any one else having a similar issue?

I have made sure that my Plex server is fully up to date.
My Chromecast is connected via Ethernet using a linksys wrt1900ac router.
the video file is MKV i tried an mp4 audio sync test file and that seemed to work fine.

I'm happy to provide anything else that would be useful but as of now I have stopped using Plex because I cant work this out.

    I'm having an issue with audio sync as well. I'm using a Chromecast Ultra. The audio is consistently about half a second delayed relative to the video. It happens with multiple file types, different encoding, transcoding on the fly, direct play, etc.

    Is there an entry in a profile xml file to adjust the audio / video offset, or some other setting that I'm missing?

    Any help would be greatly appreciated!!

    I've been experiencing exactly the same issue - chromecast ultra and plex media server connected via ethernet and the sound is slightly out out of sync...

    did anyone manage to figure this one out?
