This happens because Chrome has changed its default behavior with autoplay sounds to avoid sounds playing without the user consent in some websites.

And that's what the warning says, to create an audio context in Chrome you have to do it after a user gesture (user click, touch, button, etc.). That's how it's done in games uploaded to the TIC-80's official website, for example, you have to click on the cover image in order to play the game.

Right now sites in which you can upload your game (like itch.io) add a cover by default, so I'm not sure if adding a default cover on the generated HTML would have an impact on that. What do you think @nesbox ?

As a workaround, you can replace your generated HTML file with this one and a cover element should be added as in here. Then the game will only run after you click on the cover.

I think the idea with cover is great, will try to use your workaround.
Thank you :)

@nesbox, have you started working on this issue? If not, I have some free time right now, I could do it :)

[nesbox]

I'm not started :) pls do it if you have time.
As I see you just need to update this file build/html/embed.html.
Thank you for your help.
