Hi,  
Selecting the subtitles before the source is loaded won’t work.  
What you could do is to select the subtitles in a `sourceloaded` event handler, so the action should be executed once the source is loaded into the player and available to play.

Which platform are you using (web, Android Native, iOS Native, other) ?
