title: Playing audio data with sounddevice- Python
body: <p>I have used the following piece of code to play an audio file using sounddevice</p>
  
  <pre><code>import sounddevice as sd
  import numpy as np
  (fs1, x) = read('Traffic_stereo.wav', 'rb')
  sd.play(x, fs1)
  </code></pre>
  
  <p>But I do not hear anything! Where am I going wrong?</p>
