Answer 2

Now, it's2020

Note that (for the below reason?) Chrome has changed their autoplay policy (see https://developers.google.com/web/updates/2017/09/autoplay-policy-changes ) so you now must either:

• resume() the audio context after some (any) user interaction with the page
• or be "highly ranked" (ie trust Chrome not to stop audio by default based on user's and world's behavior)
• or (as far as I get it) user must be on origin A then click a link to same origin A and that new page of A can autoplay things.

You can play a sound using the AudioContext API and taking the source from any ArrayBuffer (ie: from a XMLHttpRequestor a File)

    window.addEventListener('load', function () {
        var audioCtx = new (window.AudioContext || window.webkitAudioContext)();
        var source = audioCtx.createBufferSource();
        var xhr = new XMLHttpRequest();
        xhr.open('GET', 'audio-autoplay.wav');
        xhr.responseType = 'arraybuffer';
        xhr.addEventListener('load', function (r) {
            audioCtx.decodeAudioData(
                    xhr.response, 
                    function (buffer) {
                        source.buffer = buffer;
                        source.connect(audioCtx.destination);
                        source.loop = false;
                    });
            source.start(0);
        });
        xhr.send();
    });

Important notes

It's worth mentioning, IMO, that this "trick" can actually be considered as a browser bug, and might no longer work at any time if browser decide that this breaks user experience/becomes a widely-used annoyance (like ads).

It's also worth mentioning that, at least on my mobile and FF 54, the sound will still be played, even if your mobile is muted...

It's also also worth mentionning that user might set the autoplay behavior to fit their wishes and needs either through the browser's usual options or through the more-advanced about:config page (autoplay behavior is set by Firefox's media.autoplay.enabled and media.block-autoplay-until-in-foreground preferences).

So forcing the audio autoplay is a bad UX idea no matter how you do it.

Answer 3

I have a lot of experience with this problem. It also applies to Javascript audio that loads before the user has had a chance to interact with the page.

HOWEVER, once a user clicks absolutely anything, it's game on. I personally recommend a full-page entrance overlay right on the front page: "Click to enter my awesome site!" If the user enters the page at all, they are doomed to hear whatever sounds you want to throw at them! :D
