Interfere with award, by the sound of it (6)
I believe the answer is:
'interfere with' is the definition.
(I've seen this before)
'award by the sound of it' is the wordplay.
'award' becomes 'medal' (medal is a kind of award).
'by the sound of it' indicates a 'sounds like' (homophone) clue.
'medal' is a homophone of 'MEDDLE'.
(Other definitions for meddle that I've seen before include "Interfere unnecessarily" , "Potter" , "Mess with" , "Stick one's nose in" , "Interfere in other's business" .)
