title: How to make app playing audio in the background (phonegap 1.5.0 on iOS)
body: <p>I have an app to play some music, using PhoneGap and html5 audio tag to play audio on iOS. previously it could play music in the background perfectly (with PhoneGap 1.0.0 for iOS), but after I upgraded PhoneGap to 1.5.0(Cordova), I can't get it play on the background anymore.</p>
  
  <p>When I press HOME button, the audio pauses. When I switch back to app, it resumes.</p>
  
  <p>I have already set the <code>Required background modes</code> in the <code>Info.plist</code> with value <code>audio</code>.</p>
  
  <p>So is there something I missed? Thank you.</p>
