Description
YouTube's mobile website doesn't have an audio track selector so they try to be helpful and pick an audio track based on your display language. Which is a nice idea although in practice that means it frequently picks an AI-generated dubbing. As FreeTube has to parse many language specific strings to extract information such as published dates and view counts, it requests everything in American English (en-US), however as we only need the streaming data from the MWEB request we are not limited to just English.
This pull request finds the original audio track in the WEB response (we can't currently use it for playback because of SABR) and uses its language as the request language for the MWEB /player request, which makes it a lot more likely that YouTube will pick the original audio track as the audio track to include in the response.
