yes, "headphone" is used often in a wrong way.
this control appears usually on ac97 chips. and the recent ac97 chips
provide the former headphone output as the "true line-out" pin for the
consumer device. hence, nowdays, most implementation uses headphone
output as the real line-out instead of the old line-out pin.
OTOH, "headphone" in emu10k1 driver refers really to a headphone
jack, for example.

so far, "Surround" (or "Rear") is used for that.
it it too amgibuous?

well, my understanding of "master" is that it's a controll for all
over other controls. i.e. if you change "master", all outputs should
be affected.
