Still sound irritated by attempt (8)
I believe the answer is:
snapshot
'still' is the definition.
(I've seen this before)
'sound irritated by attempt' is the wordplay.
'sound irritated' becomes 'snap'.
'by' says to put letters next to each other.
'attempt' becomes 'shot' (I've seen this before).
'snap'+'shot'='SNAPSHOT'
(Other definitions for snapshot that I've seen before include "Pan hosts over casual photo" , "Casual photograph" , "Bit of camerawork" , "Informal photograph" , "image" .)
