Adding audio to the hover state of a button

Has anyone been able to accomplish this? If so, how did you do it? 

I thought it would be as simple as click "Edit States" and add the audio clip to the Hover state but that isn't the case.

I then thought maybe I needed to add a trigger that would state to play media when the button was hovered over but since the audio clip was inserted into the hover state of the button, and not on the timeline, Storyline does not recognize the audio file existing.
