We might need talk about this too. If something is PA_PORT_AVAILABLE_NO,
it completely disappears from the GUI, so it can't be activated. Just
like it does not make sense to switch to a pair of headphones which are
not connected.
Is this expected?

As tanuk commented on IRC: "Headset Output" would be even better, but
that requires detecting the form-factor.
I think we do detect the form factor: at least a headset icon shows up
in the GUI.
A list of currently used names are in src/modules/alsa/alsa-mixer.c,
function path_verify.
I believe it would make sense to make these generic, possibly amend, and
use for bluetooth as well?
