Code:

        snd.pause();
        sndcurrentTime = 0;
      //snd.load();
      snd.play();
    } else {
      request.open("GET", url, true);
      request.responseType = "arraybuffer";
      request.onload = function(){
          ctx.decodeAudioData(request.response, onDecoded);
      }
      function onDecoded(buffer){
          var bufferSource = ctx.createBufferSource();
          bufferSource.buffer = buffer;
          bufferSource.connect(ctx.destination);
          bufferSource.start();
      }
      request.send();
    }

  // Function to create event listeners

        clearInterval(interval);
        if (state == 'value' && value == 1 && enabled) {
          Play_Audio(url);
          interval = setInterval(function() {
