Answers.Body: <p>Are you experiencing the problem when you are analyzing the recordings or in Viewer mode? If in Viewer mode then you have make sure you load the recordings using the Audio Data Acquisition - Use offline files (and the folder with the recordings).</p>

  Are you experiencing the problem when you are analyzing the recordings or in Viewer mode? If in Viewer mode then you have make sure you load the recordings using the Audio Data Acquisition - Use offline files (and the folder with the recordings).
  
  If the problem is when you are running the analysis in PamguardBeta have you made sure under Sound Output that you have the Channel 0 ticked and the right settings for output device type and output device name? Seems like that could be a problem if you haven't set it correctly.
