Subtitles were lagging about 8-10 seconds. I rolled back to PMS version 1.42.2.10156, docker v1.2.23 and all is well with subtitles. I…

Chris, I would be glad to assist, but unfortunately, my level of app installation knowledge for Truenas Community (Linux & Docker contaniers) does not extend beyond the normal Truenas, “Application Discover” within the GUI. . Moving forward, I plan to broaden my education.

I have tried it now and subtitles works for me with the build you’re mention

Just here to report that I was having the same issue with my Plex server running the amd64 build for Debian/Ubuntu, and that the version posted in this thread resolved it for me.

Chris, I was experiencing a subtitle sync problem with the Plex server for windows on a Roku TV and this version solved the issue. I am wondering, what the next official build is that will incorporate these fixes? Thanks so much!

I installed the 1.43.1.10498 x64 windows version you posted on the forum and it did indeed resolve the issue I reported in exactly the same scenario where I was seeing out of sync subs (SRT to WEBVTT conversion). Sorry I didn’t get back to you with logs last week like I intended. I very much appreci…

Subtitles are in synch with ROKU plex player, but they do not appear for about the first 3 minutes of movie playback. Once they show up, they are fine. Other plex players, such as the desktop player and Firestick work well with the 10498 version of PMS. ROKU app simply does not work like it should.
