title: How do I detect the audio left/right balance?
body: <p>I'm trying to detect the audio left/right balance programmatically, and there doesn't seem to be an api for getting the value of this setting. I was able to find the <code>UIAccessibilityIsMonoAudioEnabled()</code> method for detecting if the user has enabled mono audio, but I can't find an equivalent function for the audio balance.</p>
  
  <p>Anyone know how I can do this?</p>
  
  <p>P.S. Go to Settings->General->Accessibility and then scroll down to "Hearing" to set these options</p>
