Hi thanks for the responses, I guess I wasn’t clear enough though, I’m referring to Stereo outputs in the mixer not the monitor outs, I can switch and hear the monitors just fine, what I’m having an issue with is adding a second stereo output in the mixer but I can’t hear it?
The default one will play out of both sets of speakers but the 2nd one(and I guess subsequent ones I could create) is not audible, as if it’s not actually being routed out to the monitors. I was saying that this worked before I started using the control room but now it’s silent.
Hope that makes more sense. 
Cheers.
