Fixes charge for the audience (5)
I believe the answer is:
tacks
'fixes' is the definition.
(tacking is a kind of fixing)
'charge for the audience' is the wordplay.
'charge' becomes 'tax' (tax is a kind of charge).
'for the audience' shows a homophone (sound like).
'tax' is a homophone of 'TACKS'.
(Other definitions for tacks that I've seen before include "They secure" , "Approaches" , "Changes course" , "Shorts nails with big heads" , "Fixes" .)
