Forces all YouTube videos to play in their original language audio instead of the AI dubbed language. Works in both normal videos and shorts. Can be manually overridden per-video.
(2026-MAY-01 UPDATE): I believe that YouTube added a way to "turn of" (sort of... the method is slightly unintuitive) auto-dubbing natively through the preferred language setting. However, it's pretty deeply buried under 'playback and performance' settings and is hard to find, and I'm not sure how reliable that is.
