because it would require a JACK API that related to hardware mixers in
general. audio interfaces come with widely differing styles of h/w
mixers, some come with none at all. we are absolutely not interested in
attempting to have JACK, which has become as popular as it has precisely
because of the level of abstraction it represents, descend down to the
level of providing volume control.

for OSS, there are h/w mixer apps.

for CoreAudio, there are h/w mixer apps.

for ALSA, there are h/w mixer apps.

JACK does not control the h/w mixer. It doesn't do it to control the
choice of which signal stream is used for capture or playback, and it
won't do it to provide a mixing API.
