Today my coworker complained about a guy in the airport playing solitaire with the volume on. She could hear every time he shuffled and did various other motions during the game. The sounds for the most part are not necessary and could easily be muted. I leave my laptop on mute unless I am listening to something. If everyone else did this I wouldn’t get the constant chorus of the windows logon and logoff sounds.
So unless you are listening with headphones please try to mute your laptop.
