Choose or disable the alert sound
Your computer will play a simple alert sound for certain types of messages and events. You can choose different sound clips for alerts, set the alert volume independently of your system volume, or disable alert sounds entirely.
Type "Settings" into the global search bar on your desktop. Click on the resulting Settings icon, or press Enter, to open.
In the Sound Effects tab, select an alert sound. Each sound will play when you click on it so you can hear how it sounds.
Use the volume slider in the Sound Effects tab to set the volume of the alert sound. This won't affect the volume of your music, movies, or other sound files.
To disable alert sounds entirely, switch the Alert volume to Off.
