Ask audibly for quarry (4)
I believe the answer is:
prey
'quarry' is the definition.
(I know that quarry can be written as prey)
'ask audibly' is the wordplay.
'ask' becomes 'pray' (I've seen this in another clue).
'audibly' indicates a 'sounds like' (homophone) clue.
'pray' is a homophone of 'PREY'.
'for' is the link.
(Other definitions for prey that I've seen before include "Animal hunted by another for food" , "Victim, quarry" , "Animal hunted and killed for food" , "Hunted creature" , "Quarry, target" .)
