Wind instrument silent, with cracks (3,7)

I believe the answer is:

tin whistle

'wind instrument' is the definition.
(tin whistle is a kind of wind instrument)

'silent with cracks' is the wordplay.
'cracks' indicates anagramming the letters (I've seen 'cracked' mean this).
'silent'+'with'='silentwith'
'silentwith' is an anagram of 'TIN WHISTLE'.

(Another definition for tin whistle that I've seen is " Cheap, six-holed metal flageolet".)

I've seen this clue in The Times.
