Yeah, it really depends more on the device (or a specific jack on the
device) than what's physically plugged in.

FWIW, alsoft-config (released with 1.16) can also do it through a GUI.
Though yeah, I can understand why that wouldn't be a very good solution
either.

Yeah, and I'm very sorry for how long it's taking to even get a basic
HRTF extension in place. I'm just trying to juggle between what's
"enough" for apps to be useful and what I can guarantee to support into
the future -- I don't want to expose details that can change and cause a
future update to have to drop the extension due to an internal differences.
I'll just have to bite the bullet though, and likely go with a simple
enable device attribute, a device reset function (which will allow
changing it on an active device), and some status queries (to tell if
it's on, and why not if it isn't).
