is there a stainless metal flue liner rattling about in the flue? these do tend to make a racket.

the mortar in your cement and brick work is crumbling the hot and cold use will only make it worse what is it like outside holes in mortar maybe
white stains from calcium leaching from cement

is the chimney used?, what sort of fire?
lost of sand?, how much, as is it affecting structural stability of the chimney?

rumbling sounds like a liner in there and th ewind catching it and bashing it against the damp parging of the chimney.
How old the house?
