Arrive with noise to welcome in ace entertainer (8)
I believe the answer is:
comedian
'entertainer' is the definition.
(I know that comedian is a type of actor)
'arrive with noise to welcome in ace' is the wordplay.
'arrive' becomes 'come' (coming is a kind of arriving).
'with' is a charade indicator (letters next to each other).
'noise' becomes 'din' (din can mean a loud noise or disturbance).
'to welcome in' is an insertion indicator.
'ace' becomes 'a'.
'din' placed around 'a' is 'dian'.
'come'+'dian'='COMEDIAN'
(Other definitions for comedian that I've seen before include "Joker" , "Humorist" , "performer" , "scream?" , "cracking bloke?" .)
