title: App shows white screen on startup after upgrading to iOS 4.2
body: <p>For the past few weeks I have been working on an app that uses a SoundManager class that I found via the comments of this blog post:

  <p>The link to the SoundManager and tester app is provided in the comments by David Evans. I am not allowed to provide a second link so I'll mention the name of ZIP file he links to:
  SoundTester.zip</p>
  
  <p>I was very happy with this code, until iOS 4.2 was released. After updating my iPad and Xcode correspondingly, my apps that use the SoundManager class only show the navigation bar with it's title. The rest of the screen is white. It's not iPad specific behavior. I have seen the same on an iPhone4 and an iPhone 3G that upgraded to iOS 4.2.</p>
  
  <p>When running the apps in the simulator, I get the same results. The problem is that I get no error messages in the console window and no build and compile errors at all. Very frustrating and very hard to fix for an iPhone developer that started using the iPhone SDK only months ago.</p>
  
  <p>Does anyone have a clue what could have gone broken and how to fix it? Any help is appreciated!</p>
