Honestly speaking, I was at a loss how to decipher what was required of me to do! But as advised, I decided to check all connections etc.
So, I methodically did that: powered off and disconnected the speakers, re-loaded the iTunes. Blew into the connectors, reconnected, powered up and volia! It worked!!
Never look into the mouth of a gift horse, me Dad used to tell me!
So, I have left well enough alone -- and a happy SWMBO!
Thanks everyone!
