Set the default language and set default subtitles to always use available subtitles and unless you're a niche case of always changing your dub/subtitle language you should be good to go for most, if not all, cases?

This was a problem with playing some of my anime collection with EN dub and no subtitles. Now it defaults to JP dub and any available subtitles (99% of the time is only EN Subtitles, sometimes there are JP/CN and I haven't seen what happens in that scenario yet)
