title: Remove silence after playback with sounddevice
body: <p>I'm using SoundFile + sounddevice to produce short sounds.<br />
  I don't want to block so I'm using a callback in rawOutputStream().<br />
  It works fine.<br />
  The problem is that the stream do not support partial buffers and I have to fill the last buffer with null bytes. This cause a silence after every sound.<br />
  How can I remove that silence?<br />
  Thanks.</p>
