title: AdColony 2.5.3.1 Simulator issues
body: <p><a href="https://i.stack.imgur.com/5HF6B.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5HF6B.png" alt="enter image description here"></a>I just updated to the most recent AdColony framework (2.5.3.1), and have had issues with running on the simulator. Every time I try to display an ad, the app crashes. Looking at the trace, it appears to be something related to Audio for the ad. I've attached a picture below. </p>
  
  <p>In addition, the onAdColonyAdAttemptFinished delegate method is never called, only onAdColonyAdFinishedWithInfo.</p>
  
  <p>Are these known issues?</p>
