I've only used the 8 analog inputs together with Mixbus on ubuntu 12.04

How do you keep inputs (or outputs) from being active? It seems to me,
that if you can see the input in jack, that jack is streaming audio from
it even if it is all zeros (or at least servicing the port at the same
interval as any other port). So if you can see the adat and s/pdif inputs
all the time, then jack is working just as hard as if you have 18 active
inputs.
Sorry, I meant indeed connected or plugged instead of 'active'.
