title: Adding custom push notification sound ios5 not working
body: <p>I have tried to get my custom notification sound working, I have tried a caf file, an aiff file and m4r file, but none seem to be playing.</p>
  
  <p>My notification is coming through fine but the custom sound isn't playing, instead it is playing the default. My payload is:</p>
  
  <pre><code>{"aps":{"alert":"alert testing - hello!","sound":"testsound.aif"}}
  </code></pre>
  
  <p>From what I have read on here in other threads, if default is playing then the audio file isn't being found, but it is in the xcode project and I have deleted the app from my device and run it again.</p>
  
  <p>Are there any gotchyas that I may be missing?</p>
