Nought's amiss in report (7)
I believe the answer is:
gunshot
'report' is the definition.
(report can mean the sound of a gunshot)
'nought's amiss' is the wordplay.
'amiss' indicates anagramming the letters.
'noughts' is an anagram of 'GUNSHOT'.
'in' acts as a link.
(Other definitions for gunshot that I've seen before include "Fire" , "Firearm's range -- no thugs (anag)" , "Crack" , "Noughts (anag)" , "Firing of hand weapon" .)
