Welcome to my website
    

You can see audio player, so web page can find mp3 file for sure.(https://i.sstatic.net/4GERM.png)

I tried many different approaches (audio tag, embed tag, iframe, some js scripts) but I can only make audio player and I have to turn on music manually, and I can't find way to start playing music, when i enter web page. My browser is opera gx, but i tried also do this in edge with same results. Do you have any ideas how to make it work?
