title: Sound working in emulator, not in real iPhone
body: <p>Have few short <strong>sound effect</strong> samples, which play <strong>just fine in emulator, but not at all in real iPhone</strong> 3GS. Here's the code, about as-is from Apple SysSound sample:</p>
  
  <pre><code>CFBundleRef mb = CFBundleGetMainBundle ();
  CFURLRef soundFileURLRef = CFBundleCopyResourceURL
      (mb, CFSTR("mySound"), CFSTR ("caf"), NULL);
  
  SystemSoundID sid;
  AudioServicesCreateSystemSoundID(soundFileURLRef, &amp;sid);
  AudioServicesPlaySystemSound(sid);
  </code></pre>
  
  <p>When using iPhone, I can hear keyclicks and music from iTunes (not trying to use at same time as playing my sound) - but cannot hear my sound at all. Vibra works ok, so even Framework should be set up correctly.</p>
  
  <p>Tried even the SoundEffect.h/m sample code, no change. Used same sound files, but shouldn't CAF be ok, especially when it plays in emulator?</p>
  
  <p>What can I try next?</p>
