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>

回答1:

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.
    });
}

I don't know if this is still actual for you, but I still leave my comment so maybe it will help somebody else. I had same issue, and the solution proposed by @dighan on bountysource.com/issues/ solved it for me.

So here is the code that solved my problem:

var media = document.getElementById("YourVideo");
const playPromise = media.play();
if (playPromise !== null){
    playPromise.catch(() => { media.play(); })
}

It still throws an error into console, but at least the video is playing :)

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

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

回答4:

Try using a callback like this with the catch block.

document.getElementById("audio").play().catch(function() {
    // do something
});

adding muted="muted" property to HTML5 tag solved my issue

回答6:

I am using Chrome version 75.

add the muted property to video tag

<video id="myvid" muted>

then play it using javascript and set muted to false

var myvideo = document.getElementById("myvid");
myvideo.play();
myvideo.muted = false;

edit: need user interaction (at least click anywhere in the page to work)

I second Shobhit Verma, and I have a little note to add : in his post he told that in Chrome (Opera for myself) the players need to be muted in order for the autoplay to succeed... And ironically, if you elevate the volume after load, it will still play... It's like all those anti-pop-ups mechanic that ignore invisible frame slid into your code... php-echoed html and javascript is : 10-second setTimeout onLoad of body tag that rises volume to maximum, video with autoplay and muted='muted' (yeah that $muted_code part is = "muted='muted")

echo "<body style='margin-bottom:0pt; margin-top:0pt; margin-left:0pt; margin-right:0pt' onLoad=\"setTimeout(function() {var vid = document.getElementById('hourglass_video'); vid.volume = 1.0;},10000);\">";
    echo "<div id='hourglass_container' width='100%' height='100%' align='center' style='text-align:right; vertical-align:bottom'>";
    echo "<video autoplay {$muted_code}title=\"!!! Pausing this video will immediately end your turn!!!\" oncontextmenu=\"dont_stop_hourglass(event);\" onPause=\"{$action}\" id='hourglass_video' frameborder='0' style='width:95%; margin-top:28%'>";

In my case I had to wait for a user interaction, so I set a click or touchend listener.

const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;

function play(){
    audioEl.play()
}


document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });
