Correct, I can control both the speaker and headphone volumes. The
output of the mixer command becomes this:

     % mixer
     Mixer vol      is currently set to 100:100
     Mixer pcm      is currently set to  75:75
     Mixer speaker  is currently set to   0:0
     Mixer line     is currently set to  75:75
     Mixer mic      is currently set to   0:0
     Mixer rec      is currently set to   0:0
     Mixer phout    is currently set to 100:100
     Recording source: mic
