title: Select Audio device on iPhone
body: <p>Is there a way to let the user select which device they use for audio output? </p>
  
  <p>In the docs I have found that you can select which route to use by setting <strong>kAudioSessionProperty_OverrideAudioRoute</strong> to either:</p>
  
  <ul>
  <li>kAudioSessionOverrideAudioRoute_None, or</li>
  <li>kAudioSessionOverrideAudioRoute_Speaker</li>
  </ul>
  
  <p>However I would like to let the user to use their Bluetooth headset to hear the audio.</p>
  
  <p>If you look in Apple's own 'Voice memos' app, in the playback menu there is a button in the top left which lets you choose which audio device to use. When a Bluetooth headset is attached, pressing the button brings up a menu which makes it possible to select between:</p>
  
  <ul>
  <li>Bluetooth headset</li>
  <li>iPhone</li>
  <li>Speaker</li>
  </ul>
  
  <p>Is there a way to achieve this functionality using standard Apple APIs in my own app?</p>
