Feature description

If a video has audio track support, you cannot change the language the audio track defaults to. The user should be able to change the audio track language. The user should be able to do this in two ways:

1. In the 'Content' settings, if 'App Language' is set to a specific language such as English, the audio track language should attempt to default to that language.
2. There should be an audio track menu that appears when you click on the 'v' icon in the top-right of a video: this menu can be similar to the subtitles menu (which only displays the language of the subtitles).

Why do you want this feature?

If you watch a video that has audio track support i. e. the video has several audio tracks available in different languages (for example, this MrBeast video: https://youtu.be/kX3nB4PpJko), the audio track language defaults to 'Arabic' (I assume this is because Arabic is the first language in the list if the list is sorted in alphabetical order). I would like to be able to select the language of the audio track since the default language may not be a language I understand.

Additional information

Not all videos on YouTube have audio track support. To determine if a video has audio track support, watch a video on YouTube (I did this through the Firefox web browser), and click on the gear icon in the bottom-right of the video: if there is an option called 'Audio track', then the video has audio track support.
