title: MediaElement doesn't play sound effect
body: <p>I want to play a beep sound effect when the user clicks.</p>
  
  <p>I have a <code>beep.mp3</code> file added to the project (isn't in a folder). In it's properties I see <code>Build Action</code> is set to <code>Content</code> </p>
  
  <p>and this MediaElement:</p>
  
  <pre><code>&lt;MediaElement Name="beep" Source="beep.mp3" Volume="1" AutoPlay="False"/&gt;
  </code></pre>
  
  <p>then I can't hear any sounds after this:</p>
  
  <pre><code>beep.Play();
  </code></pre>
