I'd like for a YouTube video to start playing right away with the sound muted when a user opens my webpage, but when embedding it from YouTube the user has to click on it and click "play" in order for the video to start playing.
Right now I get a code like this from YouTube:
<iframe width="560" height="315" src="https://www.youtube.com/embed/M0NXSdLlaZ4" frameborder="0" allowfullscreen></iframe>
And I'm not sure how to get the YouTube video to start playing as soon as the user opens the website.
