Whilst I appreciate that you have to have Ads on the site to generate revenue, there have been a few that pop up during the last few weeks with sound in them (I've attached an image of one such ad). I actually make Flash based Ads from time to time and the guidelines are always clear that sound shouldn't be playing without either a rollover event or a user interaction. I don't suppose you can removed/do something about these...they're really ruining my Pink Floyd. Cheers! Edit: Just seen another thread on this...sorry, I didn't check before posting.
