New AXR4U - Can't get any sound out of Monitors or Headphones

I know this could be something I’m just not setting correctly on the device but, as far as I can tell, I’ve done everything right and everything looks right but I’m just not getting any sound from the unit. I’ve linked my monitors up to Line Outs 7 and 8. I don’t seem to have to change anything in the Monitor Setup Screen (or do I?). I’m not getting any sound from the phones or the PC either. The USB driver is the latest.
Any help or step-by-step instructions would be greatly appreciated.

Screen shots please…
this is a complex piece of hardware controlled with even more complex software… there is so much that can go wrong
