title: android.media.AudioTrack stereo volume 0 on one channel: still very soft sound of other channel
body: <p>When using <strong><em>android.media.AudioTrack</em></strong> to generate a sinus sound at runtime there are two ways to set the volume to 0 in the left or right channel: with the <strong><em>setStereoVolume</em></strong> method or by generating a 0 sound on one channel. With both methods, when there is a sound in the other channel, this sound is also played at very low volume in the channel with the 0 volume. </p>
  
  <p>I need no sound at all in the left or right channel when the users selects this. But it seems to be impossible. I also checked this with a few other apps that generate sound at runtime, and they have the same issue. </p>
  
  <p>The issue is not isolated to specific devices, a customer of my app observed the issue, tried several different earphones/headphones, and I could reproduce it also with other headphones.</p>
  
  <p>Is there a solution or is this just what it is?</p>
