Ok.  Now I can go to
	Sound and Video -> PulseAudio Volume Control -> Output Devices
and see the Port: choice for Speakers vs Headphones.

However, changing the Port does not change the output, it is still
coming through the internal speaker.  There is a section under "Output
Devices" for "V20 portable speakers (USB powered) Analog Stereo)" and
fiddling with that part of the menu does send a sound effect to the
external speakers, so the speakers do work and the system (in a way) is
finding them.  But I can't get the main audio signal to use them.
