To complement my last post above:
I discovered the recordings with the second program above, 'audio-recorder' were 'fake files' quiet without sound when playback with vlc or other programs. Loaded in Audacity showed only straight lines. Possibly there is some gstreamer related issue on my current system, because a warning complained about missing gstreamer plugin, when I tried to save audio as mp4. However, I don't care to debug this program issue for now.
Saving is different from recording. If you have set up Audacity for PulseAudio, then while you are sending in a signal, look at the pavucontrol input devices tabs, if you see the signal coming in. Click the "fallback" icon if needed.
The audio clips recorded with 'gnome-sound-recorder' worked fine. For one or another reasen I had to unplug the usb connection from UFO202, before playback sound could be heard in speakers and earphones plugged to the mobo backpanel jacks.
That is normal. If you plugin an USB soundcard, PulseAudio switches to that as the default input/output. In pavucontrol you can select which becomes the ative one, click on the "set as fallback" icon. I have to do that also when I plug it in. MatN
