I've never heard any audio on this site before. Is this coming from push notifications? If so your life will be much better if you disable all push notifications in your browser or go to your account preferences and turn off all the notifications. Then you can occasionally just browse to What's New and see the latest topics.Sorry a little late but that's a terrace builder. I stopped checking the forum everyday because I was tired of "IS THIS A WEED?!" I see they've changed it now to a little different audio but just as annoying.
