System sound in Windows is the sound that comes when something happens. For example, there are various types of sounds, such as an error sound when an error occurs or a sound at the beginning and end of Windows.
These sounds have little effect on the operation of the computer. It tends to be thought that it is unnecessary. For quiet PC operation, you can disable these event sounds individually or all at once.
This is a system sound only, so it has nothing to do with the sound of a movie on a computer or the usual sound when watching Youtube. Even if you set the system sound so that no sound is heard, the sound from Youtube sounds normally.
