To pause system wide audio, you don't start an intent but rather request audio focus from the system.

So when you wish to pause everything do the following (suggested in onCreate):

//The Variables we'll need to create
AudioManager am;
OnAudioFocusChangeListener af;

//I do nothing with this listener, but it's required for the next step.
af = new OnAudioFocusChangeListener() {

      public void onAudioFocusChange(int focusChange) {
          if (focusChange == AudioManager.AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK) {
              // Lower the volume
          } else if (focusChange == AudioManager.AUDIOFOCUS_GAIN) {
              // Raise it back to normal
          }    
      }

}; 

//Do the actual pause
am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int request = am.requestAudioFocus(af,
    AudioManager.STREAM_MUSIC,
    AudioManager.AUDIOFOCUS_GAIN);

But don't forget to let go of focus using:

am.abandonAudioFocus(af);
