Voices in golf clubs not quiet (6)
I believe the answer is:
utters
'voices' is the definition.
(I've seen this in another clue)
'golf clubs not quiet' is the wordplay.
'golf clubs' becomes 'putters' (I've seen this before).
'not' is a deletion indicator.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'putters' with 'p' taken away is 'UTTERS'.
'in' is the link.
(Other definitions for utters that I've seen before include "Speaks, articulates" , "Speaks, says" , "Articulates, expresses" , "Publishes" , "Speaks, voices" .)
