If all previous is confirmed, then swap the Zone 2 speakers with the Surr Back speakers to ensure they (as well as the Zone 2 pre-outs) work properly.

Thanks JDSmoothie, Yes I have confirmed that the RCA cables are indeed connected to the Zone 2 preouts. the amp is defiantly powered on. and yes I have made sure Zone 2 speakers are connected and working. I actually did connect to surround backs.
For shits and giggles I swapped RCA to Zone 3 and turned on zone 3 and it was the same. only sound to the surround backs...
I did not think this was going to be this complicated Thanks
