How to prevent audio in storyline from pausing when it leaves focus

Is there a way to prevent the audio in my storyline project from pausing when the user moves to away from the project (when focus is lost)?  I have a project with a lot of audio that users may want to multi-task while listening to, but whenever they move to another webpage or application the audio pauses.  It resumes when they move the focus back to the project however, I am looking for a way to keep playing the audio even when focus is lost.  Any suggestions?
