It was as easy as this. "Right click" on Realtek Audio Manager (which should be an orange speaker near to your clock, bottom right of your screen). "Left click" sound manager. Click sound effect 'if not already on' when equalizer appears on screen alter the karaoke setting using the up and down arrows to zero.
I hope this will be of some use to everyone with the same problem as the trouble shooter never suggested it.
