Hi,  thanks for your prompt replies :)

I'm not sure what you are asking here.  Is it:

a) Does recording/loopback work from all three input jacks if you have three
sources plugged in?
answer: no.  When I plug the first device in, the dropdown menu on the input
tab of pavucontrol automatically re-routes to the correct, plugged in jack. 
When I plug the second device in, pulse switches to the new input.  The first
input is disconnected.

or;

b) Is it theoretically possible for pulse to behave as I wish, when pulse uses
hot switching?
answer: yes, it should be possible.  If pulse created a separate input source
for each subdevice present on the card, then when one jack is plugged in, it
could grab the first available source, and flag the jack as unavailable.  When
a second jack is plugged in, it could grab the next avialable source, and flag
a second jack as unavailable.  I'm not a programmer, but this is simple logic
analogous to locking files when in use.
