title: iOS Force Audio Output only to headset jack
body: <p>I want to direct iOS VoiceOver sound to headphone even if it's not plugged in.</p>
  
  <p>In other words, while my app is open, VoiceOver sound (and other sounds played by me in app using <code>AVSpeechUtterance</code> etc.) should NEVER go to speakers, but should come out of headset, if connected.</p>
  
  <p>Can anyone suggest something on this?</p>
