does it do it if the engine is run without the aux belt?
alternator, a/c compressor, pas pump...
does it do it when stationary or just on the move?
engine vs drive train
does it do it whilst moving but the engine off?
drive train,

sounds daft but is it possible there is something inside a tyre?

A friend had something similar, it turned out to be a tyre de-laminating internally.

does it vary with rpm?
electro magnetic clutch on the a/c compressor would make a sort of "clack" if you know what I mean...

This could be coming from the wheel bearing. Just one of the balls starts to break up in one spot and makes the noise,then turns slightly in the race and the noise disappears. You won't feel any free play in the bearing.
Just a possibility.

It must be loud for you to be shouting in your post ;)

I'd swap the car for a few days with a courtesy from the garage and let one of the mechanics drive it for a while so that they can diagnose it properly.

Better that than rebuilding it from the tyres up (or getting an exorcism done... they never drive the same afterwards).

I would second this theory since I had exactly the same symptoms and it was the wheel bearing.

Hi, sorry to hear about your trouble. I too would be interested to know what the resolution is as I am getting scrapping and knocking noises when i turn my wheel so I am thinking my trouble could be a wheel bearing issue... mines not so loud that I can hear it above the music though. I use that to drown it out so i don't hear it in the hope that it goes away! :)
