I have the same issue. Subs work fine on my computer, on VLC, or even on Plex on my computer/server directly. Plex app on Roku, no subs at all.

Same issue here, Plex library on NAS running Synology DSM7.2.2, playback on Roku. Same subs that work on Plex for Windows v1.41.4.9463 and using VLC don’t display at all on Roku. Multiple videos, multiple sets of .srt files.

This is normal using Roku’s default settings… (Captioning Off)

You need to go into Roku’s Settings and make changes to captioning:

Captions mode needs to be “always on” in order for them to appear in Plex. – before anyone says (what I have read in the forum before) that they work in Netflix, etc. – it’s because these companies have special arrangements(?) with Roku to use their own caption/subtitle implementation, whereas Plex, like most other Roku apps, is required to use Roku’s captioning implementation.

If you have a newer remote that has the “Rocket” button on it, you can add captioning to the Rocket ‘launcher?’ and turn Captioning on|off without having to go into and out of Settings.

Thanks, that did the trick. Doesn’t seem to always hold the first time I turn on captions in the Roku settings, but it’s workable. Also has synch issues that aren’t present when I use the same movie and corresponding .srt file in either Windows or Android, but having that happen when the actor is speaking a language I don’t isn’t nearly as distracting as a sub or lip/audio sync when the actor is speaking in my native language (English). Not perfect, but a lot better than missing half the plot of a movie when dialogue switches to another language. Appreciate the workaround!

Sync issues with the subtitles or audio sync issues?

Thank you. This has solved my problem. I wonder how this option suddenly changed. I have multiple Roku’s and all of them changed at the same time. It used to work, then all of a sudden none of them did. I have now modified this option and Plex still has the option to turn subtitles on and off in the Plex app, but the option in Roku does have to be “Always on”
