When I open AH, I get this constant high-pitched buzzing sound at the main menu, and when I log in to an arena it's still there, but the pitch will change as I look around. I had this problem before, but it went away with a patch, now it has returned with the new patches.
I don't know what causes it, but it can get REALLY annoying, it only happens when I play this game, so I'm not sure if it's a hardware/software conflict on my end, or something with the game.
