Hi Stellania, I'm sorry if you took it bad, I wasn't criticizing. On the contrary, I appreciate very much that you share solutions with us. Only, I'm not a computer geek, so the solution you showed seems so complicated and dangerous (I get the creeps when I have to start messing with my computer settings), while turning the rotary button on your speakers does exactly the same thing without any complication... But hey... who am I... Kiss, Layla
