Be sure to check the signal path you are building. You need to
run your signal first to loop-output. You then add a loop-device
with the same id-number as a input device. The loop device always copy
data from loop-outputs to loop-inputs.

This does look a bit weird, but doesn't (or at least shouldn't) cause
problems. Loop-devices which share the same id-number, actually all point
to the same audio object.
