Prevent an iframe from playing audio

On our website we will be allowing iframe modules from other sites to display on our company's webpage. We want to use iframe sandboxing to prevent these modules from doing anything crazy like phishing attacks, but I can't seem to find a way to prevent the iframe from playing annoying audio.

<iframe sandbox=''>
  // Code from other site injected here
  // May contain something like this: <audio src='...' autoplay='true' />
  // May play sound some other way
  // Don't let any sound come out of this iframe!
</iframe>

Is this possible?

Looks like in FireFox it may be:

Updated link: https://developer.mozilla.org/en-US/docs/Web/API/MediaStreamTrack/mute_event

broken link: https://developer.mozilla.org/en-US/docs/Web/API/HTMLIFrameElement/mute

To save you the trouble of clicking the link:

The mute() method of the HTMLIFrameElement mutes any audio playing in the browser .

var browser = document.querySelector('iframe');

browser.mute();
