title: kAudioFileStreamError_DiscontinuityCantRecover in AudioFileStreamParseBytes
body: <p>I'm trying to make an audio streaming app. 
  I open stream, AudioFileStreamOpen (all ok) but when I try to parse I get kAudioFileStreamError_DiscontinuityCantRecover. Apple doc is not clear.</p>
  
  <pre><code>err = AudioFileStreamOpen(self, MyPropertyListenerProc, MyPacketsProc,
                            fileTypeHint, &amp;audioFileStream);
  
  ... // other things
  
  AudioFileTypeID fileTypeHint = kAudioFileWAVEType;
  err = AudioFileStreamParseBytes(audioFileStream, length, bytes,
                                  kAudioFileStreamParseFlag_Discontinuity);
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
