I was able to get recording working now with your comments, but I
needed one more additional step.  I had to set the Volume Control
dropdown to "Capture: ALSA PCM on front:0 (STAC92xx Analog) via DMA
(Pulseaudio Mixer)", untick the red 'X' to unmute, and raise the
volume control level to about 75% from 0%.  But now my onboard input
mic is working, yay!!!  Thanks Josh :-D
