Most users won't use the DBus interface. They will use a more friendly
program like pavucontrol. In this program, I get profiles for each
soundcard (Analog Stereo Duplex or Digital Stereo Output or Analog 7.1
output) with the possibility to select the appropriate port without
fiddling with all those mixer controls (to use front headphones for
example). This more likely to help the user than having 20 sliders in
ALSA mixer.

Well, for most users, pacmd is not the interface to use PulseAudio. This
is either the mixer of your desktop environment or pavucontrol. It seems
a good idea that the laters are using an easier terminology than
"sinks".
