Anyone can help me to solve Uncaught (in promise) DOMException: Failed to load because no supported source was found.?

Here is my code:

<script>
window.onload = function () { document.getElementById("audio").play(); }
window.addEventListener("load", function () { document.getElementById("audio").play(); });
</script>

<body>
<audio id='audio' controls autoplay>
<source src="Sounds/Myaudio.wav" type="audio/wav" />
The browser you are using does not support audio
</audio>
</body>

    Take a look at this code, it will help you

    var playPromise = document.querySelector('video').play();
​
// In browsers that don’t yet support this functionality,
// playPromise won’t be defined.
if (playPromise !== undefined) {
  playPromise.then(function() {
    // Automatic playback started!
  }).catch(function(error) {
    // Automatic playback failed.
    // Show a UI element to let the user manually start playback.
  });
}

  2. To fix error “Uncaught (in promise) DOMException: Failed to load because no supported source was found” try with this catch block

    document.getElementById("audio").play().catch(function() {
    // playback failed, let do something for users
});
