Absolutely no one. We have all our ad providers set to forbid any auto-play ads, and will follow up on any reports of these we get (in the past we have blocked ad providers who allowed these to get though).

There's a page here about how to find and send us the information we need to track down any stray audio ads. Or if you are more technically minded, you may be able to use something like firebug to find the ad code more directly. Ads tend to cycle quickly and are chosen depending on the viewer, and we aren't likely to see the same ads as you, so the more info you can give us to track these down the better.
