audio-basics fails out of the box

[madc0w]

pushing the play button results in:

index.html:81 Uncaught (in promise) DOMException: The element has no supported sources.

here:

audioElement.play();

That's probably because you're opening index.html directly from the filesystem.

If you access it through a web server (e.g. Apache), it works.

I couldn't figure out how to make it work without a web server.

You can't, due to browser security policies.

Closing. These demos don't work from a file: filesystem (security policies). To test locally, there are extensions to common code editors, like VSCode, that allow opening a page in a local web server. (I use this to test these pages when I adapted them to modern JS)
