Problem tap (9)

I believe the answer is:

hitchcock

I'm a little stuck... Click here to teach me more about this clue!

'problem tap' is the definition.
The definition suggests a singular noun which matches the answer.

'problem tap' is the wordplay.
'problem' becomes 'hitch' (hitch can mean a problem or delay).
'tap' becomes 'cock' (I've seen this before).
'hitch'+'cock'='HITCHCOCK'

Can you help me to learn more?

(Other definitions for hitchcock that I've seen before include "Sir Alfred -, Eng. film director" , "English thriller director, d. 1980" , "Alfred . . . . . . . . ., master director of cinema suspense (9)" , "Film director (the 'Master of Suspense')" , "Horrifying chap" .)

I've seen this clue in the Sydney Morning Herald.
