OK, I found my error. The Dell mini 9 doesn't have a "line in" input.be
As I started over the next day, I noticed that the input is labeled with a
symbol for Microphone.
So, I went to the Sound Recorder tab for Volume control and under the Options
tab I swithed the line in choice to Microphone.

Public bug reported:
Binary package hint: gnome-media
record options are: Mic Boost, Capture, Capture 1, Digital, and Internal Mic
Boost. doesn't seem to have a choice for Line In. Line in is not an option.
My "line in" is from a receiver I've been using to record old LPs to my
computer.
