1.) Switching power on 2.) Normal starting sound 3.) From there on permanent buzzing of the speaker
Is this normal?
Not normal. Servos may buzz holding position, but the EZ-B should be quiet.

If you have another EZ-B try taking the speaker from its shell and see if it has the same problem. If so, your amp may be querky or there is a ground loop.
What are you using to power your EZB(4) ?
I have a whole JD. I use his chest (so the original battery inside) to power the ez-b.
Battery is fully loaded.
The JD has a couple of other issues as well, but I want to work on one problem at a time. (camera not working at all. "ezbv4 camera image render error: System.ArgumentException:...")
To exclude other error sources I only use the ez-b + chassis without anything else connected atm.
Sadly I dont have an other ez-b to test with.
The noice is quite nerve-racking for me. Its not too loud, but it's the kind of noice that you cant bear for long.
Here is a video in which you can hear the noise.
Yeah, that sound is not normal. Please contact our customer Support for a warranty replacement.
In a dark room if you look closely at the JD head, can you see a Blue LED on inside the upper right portion of his head that looks like it's flickering really fast? If so, the camera is ok. It might the ez-b that has some issues (sound and video).
Nope. No blue LED flickering
The JD i got seems a bit like its made from 2nd choice parts only. Some servos got issues as well. Especially the neck and gripper servos.

did you calibrate all servo's?i had a speaker that didn work. i opened the ezb and check the speaker and springs. put all back together and all works fine.
I calibrated all servos manually and finetuned them with the software as well. Over 10 times by now for sure. Neckservo always buzzes however I calibrate him, after he moved and wont stop until i switch off the power. Clawservos cant be positioned in a way, where they are nearly closed and dont buzz like in the tutorial.
I did everything exactly like in the tutorial. Tried it many times. If it helps I can upload a video.
