audio MIDI setup information and setup?

I just got my Roland Juno-G back from service so I am going to try this question again. I get no sound when I hit playback on my Pro Tools but I can see the information playing back on the level indicators for the tracks.

- - I am connecting my imac to my synth with a UM-ONE. I think I have the MIDI studio set up correctly but here is what happens when I do the Test Setup: When I click on the output arrow UM-ONE icon in the MIDI Studio I get no response from the corresponding UM-ONE icon at the other end of the line.

ALSO, on the computer (10.9.1), in my system preferences>sound>Output, when I clck on Pro Tools Aggregate I/O (Aggregate Device) -- the message "The selected device has no output controls." appears.

I am missing something???? Anyone that can help or point me in the right direction? Thanks.
