I don't think this is a Godot issue. The link you provided clearly says it's a Chrome policy. I don't think any browser today plays audio without user interaction. Developers usually overcome this by placing a button, something like "ENTER", to actually start the game. In that button click listener, just play some click sound or start background music. Any other audio will play from there on.

Well in Defold engine this is already done in the export.

Well, adding a hard-to-customize "Run" button to exported games won't be much better IMO.

On the other hand, if HTML5 audio does not play even after interacting with the game, that might be a bug.

Then this is a bug and I have no idea how it can be solved, I updated the issue description so it gets less confusing
