Terrible Audio Sync Issue Started Today

Server Version#: 1.19.3.2764
Player Version#: Roku Streaming box

This began just tonight:

My Plex media server is on Windows 10 on a dedicated system on my LAN.
I have a Roku streaming box with Plex app.

Any video I stream now to my Roku is wildly out of sync with audio, 5-8 seconds apart. Subtitles are also way off both audio & video (it appears). If I stream these same files from another PC with Plex Web, they are fine. All these devices are hardwired through Ethernet. I have Gigabit Ethernet and Gigabit Internet.

I would have suspected the Roku device, but everything else (Netflix, YouTube, etc.) streams fine and even using the Plex app on Roku, I have streamed from a friend’s Plex server shared with me with no sync issues.

I have an Android tablet with Plex app that streams it perfectly over WiFi.

So I am at a lost to figure this one out. Again, to summarize:

  • Plex Windows 10 Server
  • Plex Web over PC plays perfectly
  • Plex app on Android plays perfectly
  • Plex on Roku plays files from friend’s Plex server perfectly
  • Roku plays Netflix, YouTube, etc. perfectly
  • Plex on Roku is 5-8 seconds out of sync on everything from my Plex server
