title: How to disable default sound effects for all my application or activity
body: <p>In my application I am using sound pool for the button click audio effect.
  The problem is that if in the device's settings "Audible selection" is ticked, then my buttons will produce two sounds: the system one and my one at the same time.</p>
  
  <p>It seems that if in each button properties I set "Sound Effects Enabled" to false, the system sound is not heard any more. But I have many buttons across a dozen of activities, plus I am adding a matrix of buttons in code, so it is rather inconvenient to set "Sound Effects Enabled" to false manually for each one of them. Not sure how I do this in code..</p>
  
  <p>Is there a more global way to stop "Audible selection" in my application or at least for the one activity?</p>
