title: How to play customized alert sound on browser?
body: <p>I would like play a customized alert sound on the browser. It will play from a .wav file I created.</p>
  
  <p>Currently, I am using AngularJS to create an alert by using <code>$window.alert(alert_msg)</code>. However, there is no sound with this function. How can I play a customized alert sound on browser when the alert box pops out?</p>
  
  <p>The AngularJS way will be preferred. Otherwise, normal javascript or jquery will be fine too.</p>
  
  <p>Thank you for your help.</p>
