Air conditioning buzz(I need your help)

[okidoki]

Hello friends. My English is not very good. Please excuse me.My car is 2018 Skoda Fabia 1.0 Style The air conditioner makes a strange sound when it is turned on. Like a buzz. I took the car to the service. They told me this sound came from the compressor. The compressor has been replaced, but it still makes a buzz. I think there's another piece that makes this sound. Could this sound be from the expansion valve?

The model of the new compressor is 5Q0816803F
As you can see, there is no change in sound. The buzz continues
Anyone have experienced this problem? How was it solved? What do you think is the source of the buzz? I would be glad if you help me.
