android - $cordovaMedia stop working -

i trying create musical instrument consisting of 8 notes, these notes represented image divided 8 areas. whenever press area plays note, if press repeatedly several areas after while app stops producing sounds. how can avoid happening?

now post code... working ionic framework.

in app.js

angular.module('starter', ['ionic', 'ngcordova', 'starter.controllers']) 

and on... interested part of app.js callback of 'ngcordova' angular.module

now on controllers.js

`

angular.module('starter.controllers', [])  .controller('soundctrl', function($scope, $cordovamedia) {   //play media   $scope.play = function(src) {     var media = new media(src, null, null);     $cordovamedia.play(media);   }; }) 

`

finally on file html this

        `  <img src="img/image.png" style="margin-top:10%;width:100%;height:auto;" usemap="#hangdrum">             <map name="hangdrum">                 <area shape="circle" coords="298,63,37,34" ng-click="play('/android_asset/www/mp3/a.mp3')"> 

`

now... sound ok , start correctly if play sound (or press different times after 10 time (more or less) stop play sound.

why? how can fix it? ;)
