title: setStreamMute never unmutes
body: <p>In the documentation, it is said:</p>
  <blockquote>
  <p>The mute command is protected against client process death: if a process with an active mute request on a stream dies, this stream will be unmuted automatically.</p>
  <p>The mute requests for a given stream are cumulative: the AudioManager can receive several mute requests from one or more clients and the stream will be unmuted only when the same number of unmute requests are received.</p>
  </blockquote>
  <p>Well, the first paragraph is true; Whenever my process dies, all of the streams I muted are automatically unmuted.
  However, no matter how many time I call <code>setStreamMute(someStream, false)</code> it NEVER EVER unmutes.
  Last time I tried calling it over 1 million times after muting only ONCE and NOTHING happens!</p>
  <p>Just to mention - If i unmute it in the same method I mute it - it stays unmuted. But on the next calls to the same method - it never unmutes.</p>
  <p>I am muting in a Broadcast Receiver onReceive method, which I start using an alarm manager. So maybe it because my app was killed during the time between the muting call and the unmuting call? (But my app still stays in the RAM)</p>
  <p>Can this problem be because I am not keeping a reference to the AlarmManager (Getting different instances each time?)</p>
  <p>Did anyone encounter this problem?</p>
