Audio from web site always on!!!
My grandkids were over playing Free Draw on the Nick Jr. website. Now I have the audio running in the background when ever I go on Safari. I have tried everything I can think of to turn it off!!! This has been going on for several weeks. I can't watch videos or listen to music without this annoying repeating sound! Thanks for any help!!
