Just did it, it all works, it passes all the tests. Only left is to split to components. Word of caution to all whom are doing this exercise:
It should be
<audio id="Q" className="clip">
<source src="someFile.mp3" type="audio/mp3">
</audio>
instead it’s
<audio id="Q" className="clip" src="someFile.mp3"/>
or if you want to display error message in the case browser doesn’t support audio
<audio id="Q" className="clip" src="someFile.mp3">
Your browser doesn't support this audio format.
</audio>
For what ever reason when you put source tag, it show an error like there’s no src attribute … And there isn’t, since test script searches for src attribute in audio tag not in source subtag.
