There’s a separate feature request that touches on this, but I think my request is different in that it is something far simpler.
Right now, you can set the preference for audio language to numerous static options, but there is nothing that would default to the original audio language. Both IMDb (TV and movies) and TMDB have this info. TVDB does not for now.
Plex can introduce a checkbox called Prefer Original Audio Language and rename the current language drop-down as “Native Language Preference”. What I was thinking is that if I prefer the original audio language, then Plex defaults to the audio language track that matches this metadata tag. If the original language is not found among the tracks, it can execute the current logic: it searches for the native language track, and if the native language is not found, it goes to the first audio track. Subtitles would be shown with foreign audio, i.e. audio that does not match my native language, which is how it behaves right now anyways. Most of this functionality would require zero changes since the relationship between the existing fields would be exactly the same with only a name change to the existing option. The only new logic would be to search for original audio language first if the option was ticked.
What I’m trying to accomplish is to just watch content in their original language. I have anime or foreign movies that may have English tracks that are dubs or commentary. I don’t want Plex to default to these tracks if I have the original audio language track as well. I chose English because most content I have is originally in English anyways, so it would capture most of the population. I also chose it so that Plex knows to play subtitles automatically if the track is not in English. By just checking this box, I’d be able to enhance the experience when playing foreign media while maintaining the functionality when playing English media.
Plex’s language settings would instantly become more versatile. This also does not seem like a major change at all, at least from my perspective.
