  // a more elegant way of determining is a volume stream can be muted and/or manually setting
  // the volume to 0 instead of using ADJUST_STREAM_MUTE. There's a bug in AudioManager that
  // causes some volume types on certain versions to not be muteable. Alarm and accessibility

  // button for these streams doesn't significantly impact user experience.
