title: Volume too low on iPhone when playing back the recorded file
body: <p>I am developing an iOS app wherein I should be able to record a sound, save it to the filesystem and then play it back from the disk. When I try to play the file off the disk, I could barely hear anything. The volume is too low. But I'm pretty sure I'd set the device volume to max. I am using <code>AVAudioRecorder</code> and AVAudioPlayer` for recording and playing. </p>
  
  <p>Could someone please point out what the issue could be?</p>
