Below is my code in aspx page to allow playing audio's of wav format in the browser but with my current code I am unable to play wav audios in Chrome browser but it works in Firefox. How can I handle this exception?

<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/DPM317.wav" type="audio/wav" />
        Your browser does not support the audio element.
    </audio>
</body>

  1. All new browser support video to be auto-played with being muted only so please put

<video autoplay muted="muted" loop id="myVideo"> <source src="https://w.r.glob.net/Coastline-3581.mp4" type="video/mp4"> </video>

Something like this

  1. URL of video should match the SSL status if your site is running with https then video URL should also in https and same for HTTP

For Chrome they changed autoplay policy, so you can read about here:

var promise = document.querySelector('audio').play();

if (promise !== undefined) {
    promise.then(_ => {
        // Autoplay started!
    }).catch(error => {
        // Autoplay was prevented.
        // Show a "Play" button so that user can start playback.
    });
}
