The incoming signal will (by default) not be passed through to the
outputs. It can be read from the computer but will not appear in the
speaker outputs. You will have to raise in input volume in the "Analog
Volume" tab of envy24control (and the outputs as well). If you do that
and send something to the inputs you should see the input VU meters
registering that. 

Do you get sound output if you send something, say start Jack and play a
pattern in Hydrogen?
