title: Volume UP and Volume Down, Mute on Google TV from Local App
body: <p>Application: a UPNP media server runing on Google TV. I'd like to raise and lower the volume of the TV and/or amplifier (as configured by the user in system settings). </p>
  
  <p>AudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, ...) does pretty much nothing when the user has configured the Google TV device to use volume control on the TV or Amplifier.</p>
  
  <p>Is there a way to simulate the effect of the Volume Up, Down and Mute keys on a Google TV remote, from software?</p>
  
  <p>I know it can be done with the Anymote protocol. But that requires pairing, even when the UPNP media server is running locally. Not happening.</p>
  
  <p>The functionality runs in a service that potentially has no active UI, so dispatching a KeyEvent isn't an option either, I don't think.</p>
