title: Use streaming audiorecord in audiomanager
body: <p>I'm trying to determine the volume level of what is currently being fed through the microphone with 'getStreamVolume' in 'audiomanager'.</p>
  
  <p>THe only available source streams listed in the documentation for audiomanager is for alarms, DTMF, music, notifications, phone ringing, system sounds and phone calls. I'm not sure how to route the microphone through audiomanager in order to get the current volume of the feed.</p>
  
  <p>Any guidance will be most appreciated</p>
  
  <p>Thanks</p>
