Stop playing audio when other is clicked and no repeat event when multi click

This is my code. I have 2 buttons one is linked to #streama and the other is linked to streamb
I have 2 problems

1. When I click any button twice it plays the audio twice (3clicks = 3time being played at the same time … and so on)

2. When I click any button the other audio must stops so it allow the new clicked button to play alone

   (function( $ ) {
   $( “#streama” ).on( “click”, function( event ){
   var hassen = new Audio(‘http://mywebsite:8000/streama‘);
   hassen.play();
   event.preventDefault();
   });
   })( jQuery );

   (function( $ ) {
   $( “#streamb” ).on( “click”, function( event ){
   var hassen = new Audio(‘http://mywebsite:8000/streamb’);
   hassen.play();
   event.preventDefault();
   });
   })( jQuery );
