How do I get audio to play when starting from a website?

I have uploaded my project to a test server. The timeline animation starts but no sound is played until I click into the window. I have tried "On start of layout: Browser focus", but no cigar. Any ideas what I am doing wrong?

Sound works from within the editor and the WebView2 export of course.

You're doing everything right, it's the browser itself. Some browsers require an action from the user every time they start, and some remember only the first launch.

It's not possible to solve this directly, so I make a start screen in the game that requires a tap to continue or a choice of control type.

You have it done correctly, after clicking on the “intro” button the map starts with sound.

Thanks for clearing that up.
