Windows has played sounds for various events for a long time now. Windows 8 also introduced some new sound events such as Metro toast notifications. But in Windows 7, Windows 8 and Windows Vista, no sound is played for desktop notifications it shows in the system tray area. In Windows XP, it played a popup sound for balloon tips in the notification area so that even if you were away from the PC or the display was turned off, you would come to know that the system was notifying you about something via balloon tips. In modern versions of Windows, balloon tips are displayed silently. Well, luckily this can be fixed quite easily.
