Pause Sound on second click

Hej guys,

based on @Chiaradesignsthings code idea, I have implemented a button / image that plays a sound when you click it. The code looks as follows:
For the html on page:

    `<audio id="play" src="https://coors-it.com/assets/Retro%20Desire.mp3"></audio>
    <a onmouseup="playSound()" outline="none()">
    	<img src="https://uploads-ssl.webflow.com/601152e54d7e2c483b639b61/6011846a631c9183e4b3ca40_Sound.png">
    </a>`

And for the footer code:

<script>
	function playSound () {
		 document.getElementById('play').play();
	}
</script>

For the second click I want the sound to stop playing or pausing.

Does anyone has an idea on how to realize that?

Thanks in advance,
Cedric
