Tries searching the forum I couldn’t find answer. It’s probably there so sorry. I converted all my blu-rays to mkv with subtitles but I chose not to burn them in. So I typically turn them on when I feel the need. I have an unraid nas and am watching my movies through Roku and Apple TV but I can’t find a way to turn the subtitles on
Have you turned them on in the roku configuration?
Go here:
Settings/Accessibility/Captions mode/always on
While the show is playing press the star button on your remote * this will allow turning on and off during the playing of the show. You may have to restart the program though. 
Thank you. This was the first chance I’ve had to try it and it doesn’t work. I’m sure it has to do with how I convert my files and my lack of understand how the plex and transcoding works. But to recap I convert all my movies to .mkv I keep the main audio which would
Typically be like Dolby digital 5.1 or 7.1 or whatever the best audio is. And I keep just the English subtitles but I do not select burn in when I convert. The reason I don’t check burn in is because I want the option to turn them on and off at will. I ASSUME burn in means it’s always on the video no matter what‽‽‽ any thing I can do that anyone can think of? Thanks again
I don’t think the Roku can display DVD and/or BluRay (VOBSUB/PGS) subtitles by itself.
It always needs the help of the Plex transcoder for that.
And that in turn means your Plex server’s CPU must be fast enough to do that.
^Correct^ - Roku wants UTF-8 text based subs.
Not sure about where these subs are coming from, but the BluRays I’m ripping seem to have those, however as I only really need the Forced type, I burn those in myself as I will always need them, so I may be missing some important details about them. I don’t really pay much attention.
The moral of the story is if the subs aren’t in UTF-8 and you don’t burn those in before hand, PMS is absolutely going to burn them in afterwards - or you won’t see them. Do something about it beforehand or make sure a video transcode (Burn) can happen and all should go as planned.

Do you know how fast of a CPU? So do I turn them on through plex settings? I’ve tried finding settings for this

How do I know which format my subs are when converting them to mkv using handbrake? I just hope I can find an option without burning them into movie

There are rules of thumb:
4000 passmark points for transcoding a full Bluray rip with VOBSUB subtitles at 1080p
If you have VC-1 video codec and PGS subtitles, you need 6000 passmark points and at least 3700 passmark points on one single cpu core (‘single thread rating’)
HEVC codec and/or 4K video require much more
So do I turn them on through plex settings?
Yes, of course. If you ripped the subtitles correctly, they should appear ready for selection on the preplay screen of the video. Or you can pause playback and activate them then.
There is also an automatic activation available.

Handbrake cannot change the format of subtitles. It can only keep them in their source format or burn them in.
You either download a fitting SRT subtitle version for your movie or you convert it yourself.
Subtitle Edit (runs on Windows) can do that.
Cayars’ auto conversion scripts can do it as well
Xmedia Recode can convert subs during a remux:
http://www.xmedia-recode.de/en/download.html
It is limited, but UTF-8 is one of them - and one of these is UTF-8:
You can tell how often I use it 'cause I don’t really know, but ‘think’ it’s SubRip.
(don’t quote me on that).
Pick one, hit the arrow thingy and push it to the right side window, run it through and in a few minutes you’ll know - just like I do.
(and for heaven’s sake don’t make them ASS or they’ll be ate up with the ASS and the Roku will puke)
