The wild goose is getting further and further away.
It's strange to record to the same device number you listened to above, but
There's only one input device on the dongle. Have you tried recording to
the laptop's mic with the sox command below? Does that work? Is your
microphone busted? Are you singing loud enough (from the diaphragm)?

I'd open pavucontrol, select your usb audio dongle's mic as your input
device, start singing (after plugging in your microphone), and see if
you can get that input level gauge to start hopping to the tune of your
dulcet tenor arpeggios on the upper end of the Richter scale.
