I would like to have mixxx take input (e.g. aux1 and aux2) from two different monitor sources.
I tell mixxx to use pulseaudio as input for both aux1 and aux2 but set channels 1-2 and 3-4 respectively.
Then I have the following showing in pavucontrol
and it's set to capture from "Monitor of built-in... HDMI"

What I'd like is the 3rd and 4th channels to capture from "Monitor of XXX" where XXX is another output device (and channels 1+2 continue to capture from "Monitor of ... HDMI")
Could a pulseaudio wizard point me in the right direction please?
