I have Subtitle mode always enabled. When I record TV (English Language) the player by default shows:
Subtitles: Unknown (Closed Captions)
However the captions don’t show. I have to choose none, and then go back in and choose the unknown subtitles for them to show.
Is this a bug in Plex, or what am I doing wrong?
Thanks.
bump…
No one?
I don’t think it’s so much a bug of the server/player but a case of bad data.
I’ve seen it occasionally on my own TV that channels show audio/subtitle channels as unknown. I suppose Plex could attempt to guess that unknown will be your local language in 90% of all cases…
If your account is configured to automatically show subtitles in English, that won’t pick up subtitles in other languages (unknown being considered a different language).
This is 100% of shows I watch. Default is unknown. I switch t none, and then back again and they work fine,
I suppose you can always manually set which subtitles Plex should show. It’s just the automated handling that won’t pick unknown subtitles if the language preference is actually English.
Here are my settings. What am I doing wrong? I’m trying to get English subtitles on an English subtitled show to play by default on every show. The setting shows unknown by default, but he titles don’t show.
@tom80H How do I manually set which subtitles show. Where is that done?
The subtitles option where it says Unknown (Closed Captions)
@tom80H I’m sorry, I don’t understand. Where it says: Unknown (Closed Captions) (which it defaults to), there is no choice to change it to anything else:
I was hoping for a place to set a default to English so that I don’t have to turn off that Unknown (Closed Captions) and then turn it back on again.
You cannot do that in Plex.
Depending on what file format you’re using, there’s metadata / container editors that’ll allow you to set the language of certain tracks (this usually goes for both audio and subtitle tracks).
Personally I’m using MKVToolNix for MKV and Subler for MP4 containers. The latter is only available on Mac IIRC. I’ve learned that mp3tag is also rather powerful and will allow you to work with many more container formats than the app’s name implies 
@tom80H Well that explains why I couldn’t do it : ) These are recordings of live TV off the air, if that makes any difference… Plex brings them right in from my HDHomeRun,
Even for recorded media, there’s files and those files can be edited.
If you change the language tagging for a track, Plex will usually pick this up if you Analyze the item in your library.
I know you can tag the tracks of a .ts container using FFMPEG… though that’s a bit tricky as you need to figure out the ID of the tracks so you can tag them via the command line.
In the end what bites you here is the broadcasters not tagging their audio/subtitle tracks accordingly. 
Tom , doesn’t MKVToolNix support ts files and you can Tag the subtitles and remove all unwanted subtitles before re muxing.
IIRC it does but only if you mux your file into an MKV output.
Ok, I use mkv almost exclusively as a container. I have no issues with embedded metadata that way. Tagging Forced subs as the only subtitles works for me.
Cheers
Closed captions are not exactly the same as subtitles. CC’s are encoded in the video stream, instead of being a separate data stream. Therefore you cannot tag them with the above mentioned tools that easily.
The only “clean” solution I know is the most laborious too 
@OttoKerner Ahh, thanks for the clarification, BUT that doesn’t explain why the setting for CC has to be turned off and then on again for them to appear… THAT is the problem.
bump… CC defaults as on. Why do I have to turn it off and then on again to get CC?
Another bump… is this normal procedure?
