Noise about king drinking coffee (7)
I believe the answer is:
clatter
'noise' is the definition.
(clatter is a kind of noise)
'king drinking coffee' is the wordplay.
'king' becomes 'CR' (short for Carolus Rex, King Charles in Latin).
'drinking' is an insertion indicator.
'coffee' becomes 'latte' (I've seen this before).
'cr' enclosing 'latte' is 'CLATTER'.
'about' acts as a link.
(Other definitions for clatter that I've seen before include "(Make) a rattling noise" , "Loud rattling noise" , "noisy commotion" , "Make a rattling sound" , "Rattle" .)
