Hi I received my RMBP yesterday and have noticed when I play music or watch a youtube video at full volume I can hear a weird sound coming out of the speakers especially when playing the RMBP TV ad. So I was wondering if some RMBP owners could play this apple video at full volume and tell me if they can hear the weird noise coming from the speakers when playing it at full volume http://www.apple.com/uk/macbook-pro/#macbookpro-tv-ad
