title: Web Audio API: Pan audio (left/right) + controlling gain
body: <p>I want to create a very basic AudioContext()-instance playing a sound either on the left or on the right channel.</p>
  
  <p>I know, there is already an answer about this here: <a href="https://stackoverflow.com/a/20850704/1138860">https://stackoverflow.com/a/20850704/1138860</a></p>
  
  <p>My problem is, I have to control the gain via a GainNode.<br>
  Whenever I conntect the GainNode, it makes the left/right channel to output sound again.</p>
