Plex Media Player - Settings question

In the Windows 10 App for Plex, Where is the option for the audio? I have a movie that plays in DTS in another player, But for Plex, It does not play in DTS. The application that I have for Plex, From the Windows Store has no option for “Audio” Specifically, At least in the settings section, As far as I can see.

The Windows store Plex app is very limited with what it can do with audio. What audio settings are you looking for?
