Does this noise exist with all image resolutions?
Also, does it change when changing the frame rate or the light
frequency?

Yes.

Today, I can not reproduce the same noise. Only when I put my hand
near the camera. I tried to record it, but there is no sound.
The sound is only on the speakers.
I muted the output and disabled the "Webcam Classic", the same interference.
The camera don't have an microphone,

there is no need for snd-usb-audio on this model.
