Change disclaimer for the audience (5)
I believe the answer is:
waver
'change' is the definition.
(waver is a kind of change)
'disclaimer for the audience' is the wordplay.
'disclaimer' becomes 'waiver' (I've seen this before).
'for the audience' shows a homophone (sound like) (how an audience might hear it).
'waiver' is a homophone of 'WAVER'.
(Other definitions for waver that I've seen before include "Falter, be irresolute" , "Hesitate" , "Be irresolute; flicker" , "Show hesitation, begin to give way" , "Not be sure of" .)
