Capture embeded click counts of an audio file within a randomised loop

Hi,
My test needs to count how many times a participant listens to an audio file. I used timing in qualtrics, but timing makes mistakes in recording the results. For example, it also counts clicks when people click the blank page.
So I would like to use javascript to solve this problem.
How do I instantiate embedded data inside Javascript? My current survey randomly chooses a series of audio files and questions in loop& merges (which has three fields; i.e., field 1 is audio files, field 2 is a yes/no question, and field 3 is a picture), and I would like click counts to be counted and named in accordance with the specific question dynamically, is this possible?

My current code in HTML is below

Press the button to play the audio file. Once the audio file has finished playing, you will be able to play it again.

Play Sound File




Javescript is below
Qualtrics.SurveyEngine.addOnReady(function() //OnLoadComplete
{
//Create variables
var seconds = 0;     //Create emtpy seconds int
var playCount = 0;    //Create iterator to count times played
var sound = document.getElementById("sound1"); //Get this audio file based on ID defined in HTML
sound.volume = 1;

//Count upwards in seconds
const interval = setInterval(function()
{
   seconds++;
    Qualtrics.SurveyEngine.setEmbeddedData("_secondsCount", seconds); 
   }, 1000);

//Function created to play sound and record input
function playSound() 
{
playCount++;                                  //Iterate counter
console.log("Sound playing");   //inform console
  console.log("Times sound played:" + playCount); 
  var button = document.getElementById("audiobutton"); //button from HTML reference
var question_id = this.questionId;

var embeddedDataFieldname = 'playCount' + question_id ;


  button.disabled = true;                          //Disable while audio is playing
button.style.background='#110000';
  sound.play();                                  //play the sound
  
  //update _playCount embedded data to record this result
  Qualtrics.SurveyEngine.setEmbeddedData(embeddedDataFieldname,this.question); 

};

//This is the reference into the HTML button which runs the function
jQuery("#audiobutton").on("click", playSound);

//When the sound has finished playing, add one to the counter
  sound.onended = function() 
  {
     console.log("Sound finished");

  
  var button = document.getElementById("audiobutton"); //button from HTML reference
  button.disabled = false;                          //reactivate button 
    button.style.background='#4CAF50';
}
});

Qualtrics.SurveyEngine.addOnUnload(function() //OnUnloaded
{
clearInterval(interval); //release function when page is killed
});
