Which pins on WM8753 are affected by what in order to make this buzz?
Wolfson micro headquarters is in Edinburgh AFAIK. Probably you'll find someone there who might be interested in your findings on that. Please don't forget to specify things like amount of soldering tin between chip and PCB and distance of chip upper surface to can lid, when starting investigation, so the results about chip-internal effects when applying RF to single pin are reproduceable.
For the rest of us, the simple rule "there must not be *any* RF *anywhere* on WM8753" should suffice to do a decent working buzz-free design.
