Thank you for fast answer. Thank you for provided solution (snippet), it is exactly what I need but can not managed myself to write this snippet.

epirozok,
Sorry what does it mean “solved”? It could work for you in chromium browser but it doesn’t work in latest version of Chrome which is a very popular browser.

Mauro Vicariotto, hello! Because you have paid for your special version of software may be you can try to contact author “Bertrand du Couédic” via his email [email protected] ?

Friends, thank you for your comments and interest to my topic. Finally I have found why it work in this way in Chrome (I mean does not work properly!) as was described above.

I found the reason on Internet.
“Chrome’s autoplay policies will change in April of 2018 and I’m here to tell you why and how this is going to affect video playback with sound. ”

You can read more here:
https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

It means Chrome blocks autoplay function for audio/video itself! And to make audio autoplay “User has interacted with the domain”, so this is why audio starts to play after clicking on menu item, for example. Seems there is no solution right now. ??
Any solution for Chrome will mean cheating with Google algorithms. Even if the author comes up with a solution for Chrome autoplay blocking, we do not know whether he will implement it (from the ethical point of view).

But it works in IE/Mozilla still! And also could became blocked anytime.

So the problem not in this plugin.

On the other hand, it is very unpleasant that the author does not respond to the forum topics (even to paid users).
