Hear no sound from stable (5)
I believe the answer is:
neigh
'sound from stable' is the definition.
(horses go neigh)
'hear no' is the wordplay.
'hear' shows a homophone (sound like).
'no' becomes 'nay' (archaic form of 'no').
'nay' sounds like 'NEIGH'.
(Other definitions for neigh that I've seen before include "Negative sound of horse?" , "Horse's noise" , "The noise of a bay" , "Comment from stallion" , "Beastly sound" .)
