There is a stereo input jack for each of rear mic, front mic and line in.  Each
of these has a separate hardware subdevice that is recognised by ALSA.  I want
to be able to plug, for example, Chromecast into Front mic, phono amp into rear
mic, and TV into line in.  This is possible in hardware, it should be possible
in software.

One solution would be to have a mixer source for all three subdevices, another
(preferred for me) solution would be to create a separate input source for each
hardware subdevice.  This would allow me to use default.pa to route particular
inputs to particular outputs via particular loopback modules.
