Ask HN: What is the best way to start autoplay?

As you know, some browsers prevent 'autoplay' in <audio id="sound" src="track.mp3" autoplay></audio>. I have 2 solutions and need to choose only one:

1) <body onclick="document.getElementById('sound').play();">

VS

2) document.addEventListener('click', musicPlay); function musicPlay() { document.getElementById('sound').play(); }

Thank you.
