I need to write code where, when you click on an image, an audio file starts playing. If it is clicked again the music stops.

I tried to do it with this code:

<audio id="audioFile" src="audio/sunflower.mp3"> </audio>
<button id="player"> 
    <img src="images/cassetta.jpg"> 
</button>

document.addEventListener('DOMContentLoaded', function() {
  let playing = false;

  document.getElementById('player').addEventListener('click', function() {
    let audio = document.getElementById('audioFile');
    if (playing == false) {
      s.play();
      playing = true;
    } else {
      s.pause();
      playing = false;
    }
  });
});
