Testing audio functionalities in Google Actions simulator

I'm writing my first action for the google home, which involves playing an audio file. I was able to get the playback going by returning a MediaObject, however, when I use the simulator to test the action, the "Pause" command is not recognized. I'm aware that I cannot implement a Pause intent and that no callback is issued when the user says "Pause", but I would've expected for the Simulator to respond to it. Any idea where I'm going wrong?
