@tubetime Thirty odd years ago when I was one of a couple of dozen people at our company with a sparcstations on our desks we had a script which was run by the receptionist which sent a recording of her calling out "the sandwich lady is here" to all the sparcstations. This produced a splendid cacophony of slightly, and occasionally very, out of time renditions of the same phrase to go through our building.
But it worked.:Everyone got lunch.
And the receptionist didn't have to walk through the building or make lots of telephone calls.
So that's an actually useful example of play allowing anyone to make sounds on other people's workstations.
