A sound story (6)
I believe the answer is:
report
This clue is a double definition.
'a sound' is the first definition.
(report is a kind of sound)
'story' is the second definition.

(Other definitions for report that I've seen before include "Complain about - account" , "Written account" , "Work for a newspaper" , "Narrative given by porter" , "Sharp sound of a gun firing" .)
