The old SGI IRIX workstations had sound effects. (the OS is featured in the original Jurassic Park film with the very silly 3D file manager)
It was literally like the hacker movies and predated most of them. Keystrokes, button presses, everything made a little noise. My first boss talked about the horror of the university computer lab full of them before they turned all the sounds off (as well as the absurd cost of outfitting that lab).
With a daemon approach and clever integration within applications that handle missing fifo correctly, all you need to do to get rid of the sounds is just stop the service. And it's also configurable, so you can set what actions actually do produce sounds.
