AFAIK this really depends on hardware. Above screenshot is from my
laptop (Centrino 2, Intel HDA on Connexant chip), I once saw this dialog
on computer with EMU10K card. The list was bigger than screen and there
were various combinations.
So, if the card supports simultanous output to SPDIF and analog, there
will be two ink available. This is how I undestand profiles :)
Another funny thing, my laptop has only analog jack for headphones.
Somehow chipset capabilities (or non existand dock capabilities) are
exposed, not the physical outputs.
