title: Is it possible to manage audio output on chrome os?
body: <p>I'm currently developing an android app on a chromebox.
  This application must be able to send audio output to different USB devices despite the audio configuration of the chromebox.</p>
  <p>From the android <a href="https://developer.android.com/guide/topics/media-apps/volume-and-earphones#fixed-volume" rel="nofollow noreferrer">documentation</a> :<br>
  <em>Some devices (like Chromebooks) have volume controls but do not allow apps to use the AudioManager methods described above to change the level of an audio stream.</em></p>
  <p>This seems to be only for the level of an audio stream. I didn't find any restriction about the redirection of an audio stream.</p>
  <p>I found this <a href="https://issuetracker.google.com/issues/172344922" rel="nofollow noreferrer">bug</a> on the google issue tracker :<br>
  <em>Yes, essentially apps cannot use the AudioManager methods, they must use setVolume.</em></p>
  <p><strong>Is it not possible to redirect audio stream to a specific USB device for android app on a chromebox?</strong></p>
  <p>Please let me know if you guys find something about this.
