Recently google changed its autoplay policy for Chrome:
To resume the whole thing: now unless the user actually clicks the Html Component it won't play any type of audio. This completely shut off ANY possibility to play with audio using a Wix Component + Html component (ie.: play audio when user clicks a button, play audio when page loads).
Now the iframe component must receive permission to allow autoplay. I know that Wix uses and <iframe> sandbox. So I would like to ask for an allowAutoplay function for the html component the same way it has the allowFullScreen one.
