I frequently switch between monitors (output 1/2) and headphones (output 3/4),
and doing so on hardware is a 2 or 3 step process, so I was hoping there is a
way to get pulseaudio to see output 3/4.
Here is what the relevant sink from pactl:

I was able to see all 12 inputs in ardour. `aplay -L` looks... well, not quite
right, this is multi-channel and not a surround card:
