why does the phone still make sound via the external speaker when plugging in headphones? i understand that it's telling u that the Beats audio is on but shouldn't it be silent and only make a sound via the headphones?? more annoying is that when you receive a call, text message or email notification, the external speaker still makes a sound. wtf? the external speaker should be muted when headphones are plugged in. the only sound that should go off is alarm which goes off even if the phone is muted which makes sense. is there a workaround for this???
