Something to play? Opener not interested, reportedly (8)
I believe the answer is:
keyboard
'something to play?' is the definition.
'opener not interested reportedly' is the wordplay.
'opener' becomes 'key' (I've seen this before).
'not interested' becomes 'bored' ('bore' is the opposite to 'interest').
'reportedly' shows a homophone (sound like).
'bored' is a homophone of 'board'.
'key'+'board'='KEYBOARD'
(Other definitions for keyboard that I've seen before include "one lays hands on" , "Body rake (anag.)" , "way to enter data" , "Component of piano" , "facility for writing" .)
