title: Sporadic audio playback issue on Voxeo Prophecy (audio playback conflict)
body: <p>Prophecy version: 14.5.2</p>
  
  <p>I am using the following CCXML line to playback audio files over a phone call:</p>
  
  <pre><code>&lt;dialogstart src="'NoResponse.wav'" type="'audio/wav'"/&gt;
  </code></pre>
  
  <p>This works the majority of the time. However sometime a few threads will begin having errors during the playback of an audio file, this doesn't seem to be tied to any specific audio file. In the logs I get a SIP event error with the following details (only showing relavent bits from log):</p>
  
  <blockquote>
    <p>CTStream/Failed to read from VIO accessor.
    CTStream/Transcoder:failed to read from backbone.
    Reading from playback stream has failed.
    name="error.dialog.notstarted"  reason="audio playback conflict"</p>
  </blockquote>
  
  <p>Any information the leads to the resolution of this issue would be greatly appreciated. I have not found any information on this in the Prophecy documents. </p>
