Ads with sound playing automaticly

You you please stopp putting ads that play sound automaticly on the frontpage?

Took me like 5 minitues to figure out from where it is coming.

The lagging drop down ad on the top is bad enough, please don't send us searching for the origin of the sound.

If it helps you to track it down:

It was an ad for Diablo 3
