Changing Audio Track
Some movies or shows have dual audio. In those cases you can change the audio track of the media by pausing whatever you’re watching and clicking the “Playback Settings” button, which looks like two sliders.
You can then choose which audio stream you would like to hear. This is not always available, and sometimes you may just have to turn on subtitles.
Default
If you would like the default audio track to be a language other than English, then you can change the default language from the main menu.
Settings > General > Change your default language of choice.
