Having the following content of editor’s area of this challenge
<!--
HTML5's audio element gives semantic meaning when it wraps sound or audio stream content in your markup. Audio content also needs a text alternative to be accessible to people who are deaf or hard of hearing. This can be done with nearby text on the page or a link to a transcript.
The audio tag supports the controls attribute. This shows the browser default play, pause, and other controls, and supports keyboard functionality. This is a boolean attribute, meaning it doesn't need a value, its presence on the tag turns the setting on.
Here's an example:
<audio id="meowClip" controls>
<source src="audio/meow.mp3" type="audio/mpeg" />
<source src="audio/meow.ogg" type="audio/ogg" />
</audio>
Note: Multimedia content usually has both visual and auditory components. It needs synchronized captions and a transcript so users with visual and/or auditory impairments can access it. Generally, a web developer is not responsible for creating the captions or transcript, but needs to know to include them.

I get " Your audio element should have a closing tag."
Removing HTML comment from the above fixes the problem. This is erraneous behavior of this challenge I guess - content of comment affects result of challenge, while it shouldn’t.
You may wonder why I included the challenge text? Well, I am saving for myself each challenge for future review. In some cases I include in comment all or part of challenge description for learning purposes.
