title: Adjusting Volume using JLayer
body: <p>me and a friend are programming a MP3 Player as a schoolproject. We are nearly finished and now stuck at the point where we try to programm a function to change the volume of the player. 
  We are using:</p>
  
  <ul>
  <li>AudioDevice</li>
  <li>AdvancedPlayer</li>
  </ul>
  
  <p>I know someone else asked the same question allready but I did not quite get the solution and I didn't want to respond to such an old question so I thought I'm just gonna ask again.</p>
  
  <p>Cheers
  Timothy</p>
