Solved

Have you tried unpluging and plugging the Speaker ISO just incase it has come loose.
Also check obvious things like the fader. Youl be surprised how many people i have met that have changed the fader and forgotten lol.

I've tried both of them, no joy unfortunately!

Ahh it's ok, ive fixed it
One of my speakers connection wasn't in properly lol

Cool nobody would wish no sounds on anybody lol.
