pasta VS plex-audio-subtitle-switcher

My guess is that for both tracks the actual language code used is just Spanish, and it's just the title that indicates esp versus lat. In that case, since there are multiple tracks with the same language, Plex will pick the first track available. You might have to use something like PASTA or Plex Auto Languages for better control over selected audio/subtitles.

It might be easier to use something like PASTA to bulk-select the specific track you want, or Plex-Auto-Languages, which will give you a more Netflix-like experience where changing the track of one episode will go through all episodes in the season/show and automatically select a track of the same language/name if available.

I use https://www.pastatool.com/ for setting the defaults. You can chose to set which track and subtitle is the default for a show or movie.

Outside of that, you'll have to use something like PASTA or Plex Auto Languages to bulk-update the selected audio/subtitle stream.

Since you have the remux, I'd just keep that, and select the right subtitle/audio stream when playing the file back. The major benefit there is that you don't need to have two copies of the same video stream just for different audio/subtitle tracks. The major downside is that if the audio/subtitles you want aren't the default, you have to manually change it for every episode, so for the best experience I'd combine that with a third-party script like Plex-Auto-Languages (a script that will change the audio/subtitle stream for all episodes in a season/show when one changes) or PASTA (a one-time bulk operation tool).

Not within Plex itself, but you can bulk-update a subtitle track for a season/show with PASTA. Plex-Auto-Languages does something similar by changing tracks for an entire season/show if you change the track for a single episode.

Ever since I was recommended this script for batch setting audio/subtitles on a show, I've used it religiously every time I'm about to start a new show to enable some specific subtitles or change the language. It's a super handy tool, but I'm lazy. I didn't want to remote into my plex server, manually run the script, find the right show/season, AND select the proper audio/subtitle streams every time. Luckily, I'm not only a lazy person; I'm also a bad programmer.

This might be useful. I'm not sure this is the right/current tool. I know there's something prebuilt out there but haven't done it myself. Someone else will probably chime in.

If you’re okay with a command line utility, I use: https://github.com/gstacks13/plex_set_tracks

the only ways i’ve been able to find to deal with this are pastatool and this script

This may not be a perfect solution, but I personally use it per show for anime with .ass files and it does wonders. Allows setting which sub and audio track per season or for the whole show. https://github.com/gstacks13/plex_set_tracks
