I need to embed an internet archive game (archive.org) in an iframe inside a web page. The game in question looks good but I can't get it to have sound.
I leave you the link to the game: https://archive.org/details/arcade_ckong
And this is the HTML test code:
<body>
<iframe src="https://archive.org/embed/arcade_ckong" width="560" height="384" frameborder="0" webkitallowfullscreen="true" mozallowfullscreen="true" allowfullscreen></iframe>
</body>
