I love this: Random sounds that still play when the sound is off has been a problem on the Mac since WoW 1.00, 2 full years ago. I noticed it in february 2005. Good to see they're on top of things! There are two main things that would still play...the mechanical hum while in Ironforge and mob voices. Even with all the sound off you'd still hear, for example, Ragnaros's dialogue in the molten core. Doh!
