Modern computers have an internal built-in speaker which, at least for Windows, emit a basic beep, which is usually a simple beep, in case we do not have some external speakers connected.
So, if your computer runs them Windows 10 and does not have peripheral speakers or the program connected driving audio is not working or is disabled, then you may sometimes hear an annoying beep, such as when a message box appears with a notification. If you are disturbed by this sound signal and you are interested in turning it off, see below how you can do it.
Disable the sound of a PC speaker in Windows 10:
1. Right-click the Start button on the taskbar.
2. On the Start button menu, select the Command Prompt (as Administrator). A command line window with elevated privileges opens.
3. Type the following command:
sc stop beep
This command will disable the sounds immediately.
4. Now, type the following command:
sc config beep start = disabled
This command will permanently disable beep sound even if you restart the computer.
In Windows 10, the computer speaker sound is controlled by the driver and a service called 'beep'. You can find it in the Registry at the following point:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Beep
By tinkering with this service from the command line you will see that you are actually tinkering with it price of the DWORD “Start”. The disabled parameter corresponds to a value of Start = 4, while its default value was Start = 1 which corresponds to the “system” parameter
Writing at the command prompt
sc config /?
you will get help with all the possible parameters of this command.
Good Luck.
