dbarron I do mute all the sounds of my computer apart from the music/video player. Why should a computer be noisy? I like quietness, what's the aim of having a noise when you turn on your computer, turn it off, etc...
Why not adding a sound when you turn off your car, when you turn on your TV, when you turn on your shower, when you open a door in the house, when you sit on the toilet, when you open a book, when you turn on/off the light, when the heating system starts/stops....
