How to turn off PCBeep when it is not in the settings?

Question

Audio

I have a problem on a new computer, the headphones are noisy. The same situation was with an old computer with a card from Realtek. There everything was decided by entering the device settings and turning off the "PC beep", that is, the computer signal. Here, with IDT HD audio, there is no such setting. Generally. Tried through the registry but did not work. How can I do this, tell me!

Answer 1

Where does such confidence come from that in a completely different computer there are pickups from a beeper?
The laptop has a rather dense layout, any other device can fon.
