Make sure that you have a plan in Vis. structure with "Usermode visualization" parameter set to "Show, make default"

Hi,

This is a very old script and was used before we had custom JS.

Due the implemantation of custom JS we had better options to implement things..

Use this custom JS instead of the old script above:
Code:
// Closing current script section to add elements
</script>
<audio id="SE_Audio" style="display: none;"></audio>
<script type="text/javascript"> // Starting new script section after adding elements 

$(function(){

   // Table with parameters address, audio URL, repeat, interval in ms
   var AudioTable = [
     { address:"32/0/0", url:"/user/beep.mp3", repeat:true, interval: 2000, intervalHandle: 0},
     { address:"32/0/1", url:"/user/beep1.mp3", repeat:true, interval: 2000, intervalHandle: 0},
     { address:"32/0/2", url:"/user/beep.mp3", repeat:false, interval: 2000, intervalHandle: 0},
     { address:"32/0/3", url:"/user/beep1.mp3", repeat:false, interval: 2000, intervalHandle: 0},
