Can we autoplay a embeded video with sound using Youtube Iframe API

I have observed that videos on WhatsApp and Inshorts are automatically playing with sound. How can we achieve this functionality using the Iframe Player API?

 new YT.Player("player", {          videoId: "sGPrx9bjgC8",          playerVars: {            playsinline: 1,            autoplay: 1,            color: "blue",            mute: 0,            enablejsapi: 1,            loop: 1          },          events: {            onReady: onPlayerReady          }        })

this doesn't worked
