Steps to reproduce the problem:
1. Close all tabs until browser exits.
2. Start the browser again.
3. Open a page with the following code:
<!doctype html>
<html>
<body>
<input type="file" onchange="onChange(this)">
<script>
function onChange(i) {
const f = i.files[0];
const url = URL.createObjectURL(f);
const v = document.createElement('audio');
v.src = url;
document.body.appendChild(v);
}
</script>
</body>
</html>
4. Choose a *.mp4 file
What is the expected behavior?
no sound produced
What went wrong?
it produced a sound (a click) coming from the speakers

Video Acceleration Information
It occasionally reproduces itself without precautions like restarting browser, but after restarting the browser without the test page I can reproduce it every time. I can hear occasionally this sound on other sites. Like, Stack Overflow. Probably after they've added the Duck. I think I'm not using PulseAudio. I can't reproduce it in Firefox. I tested it with two mp4 files, and can hear a click with both of them. Feel free to ask for more information.

Unable to reproduce this issue on reported version 65.0.3325.162, and on latest stable 65.0.3325.181 using Ubuntu 17.10 with below steps. 1. Saved above code as .html. 2. Freshly opened browser and opened .html file. 3. Clicked on choose file and selected small.mp4 file and didn't observe any click. Attaching files used to test this issue. @Reporter: Please let us know if we miss anything. Also please provide us sample files on which you are seeing this issue. Thanks!

First, I noticed I probably provided a temporary version of html code. I was experimenting with audio tag as well. There is supposed to be video:
const v = document.createElement('video');
Second, I can hardly reproduce it now. I was able to reproduce it with your video, but only once. With my videos it doesn't reproduce better. Also, I heard the click when switching (Ctrl-Tab) from a tab with your video to tab with google.com. Now it occasionally reproduces when opening new tab. There's Google Search page with a video there.
It was unclear what to put in "OS Version" field. I'm running Arch Linux, it has no version. It's a rolling release distribution. And the issue might have something to do with PulseAudio not being installed.

@Reporter: As per comment#3 it is understood that ('video') has to be there in html code, But we aren't very clear about replacing 'audio' or adding 'video' along with the code. It would be highly helpful if clarified on this. It is also mentioned that issue is not reproducible consistently from your end too.., From that statement can we close this issue?
Thanks!

Here's the code as I meant it to be:
<!doctype html>
<html>
<body>
<input type="file" onchange="onChange(this)">
<script>
function onChange(i) {
const f = i.files[0];
const url = URL.createObjectURL(f);
const v = document.createElement('video');
v.src = url;
document.body.appendChild(v);
}
</script>
</body>
</html>
> It is also mentioned that issue is not reproducible consistently from your end too..,
unfortunately, yes
> From that statement can we close this issue?
it probably makes sense
