Sound and smell coming from game (4-4)
I believe the answer is:
ping-pong
'game' is the definition.
(ping-pong is a kind of game)
'sound and smell' is the subsidiary indication.
'sound' becomes 'ping' (ping is a kind of sound**).
'and' says to put letters next to each other.
'smell' becomes 'pong' (I've seen this before).
'ping'+'pong'='pingpong'
'coming from' is the link.
(Other definitions for ping-pong that I've seen before include "Sport played on a table" , "A type of table tennis" , "27 ac tennis" , "Table-top game" .)
