Background animation on a page needs separate audio track?

Hello all,

I have a question about background animations on landing pages and what we need to have in place.

I’m aware of the pause/stop/hide requirement<https://www.w3.org/WAI/WCAG21/Understanding/pause-stop-hide.html> (which we are not currently meeting ☹) and I need to sort out.

In the case where we have a short video loop, do we also need to provide an auditory description to be accessible? These are quite new animations and have triggered this accessibility check “object link to multimedia file require equivalent alternatives (e.g., captions or auditory descriptions of the visual track).” I would really appreciate to know whether I should ignore or try and accommodate this check in some way to meet Level A and AA standards.

It looks like the below:

Thanks for all of your help.
Kind regards
Louise
