Safari doesn't play any audio.

Could someone with Safari test this:

I get only an error:

[Error] Failed to load resource:

the server respond with a status of 404 ()

It works just fine with FireFox on this Mac.

Can someone confirm that it doesn't work?

I just tried it with safari on my iPhone... it worked fine (except the button was hard to press because it was small, and there seemed to be a 3 or 4 second delay from the time the button went green and the sound started).

it is an old iPhone 5S, running iOS 12.0.1

Thanks for testing. It seems it was the Mac. It's working now.
