Why did you change from display:none to an empty element? Browsers have already implemented it as display:none, and I think it's a nicer behavior for authors who want to style audio elements that expose controls (e.g. giving a border) without affecting audio elements without controls.

I suggest forcing display:none, like with <noscript>.
