Thank you (and robot1).  I installed pavucontrol and followed your
instructions.  The volume was selected in the middle (100%).  We see a
volume meter going up and down as expected with either headphones or
speakers selected.  When mute is pressed the meter looks dead, as
expected.

It also shows line-out is unplugged and headphones are plugged it.

Any thoughts.  I appreciate the help.
