Register new arrival in family after audible dissent (4,2)

Ross

I believe the answer is:

book in

'register new arrival' is the definition.
(as in booking in to a hotel)

'family after audible dissent' is the wordplay.
'family' becomes 'kin' (synonyms).
'after' says to put letters next to each other.
'audible dissent' becomes 'boo' (sound of disapproval).
'kin' put after 'boo' is 'BOOK IN'.

'in' acts as a link.
