Youtube Embed Video Autoplay Is Not Working With Sound Unmuted In Google Chrome, While It Works For Firefox

I am trying from 3 days to autoplay the youtube embedded video in google chrome with 'Sound Unmuted' but it is not working. While the same video with same code works in mozilla fir

Solution 1:

You need mute set to 0 and after the video starts you need to make a trigger at 0:01s to rise the volume back to 40.
