title: How do you play sound through a specified audio device on Android?
body: <p>I need to be able to play a sound through a specific audio device, rather than the default audio device.</p>
  <p>The app lives on an Android media box, and the default audio device is the HDMI output. However, I need to be able to play a sound through a different connected audio device (such as a USB or Bluetooth speaker).</p>
