In pavucontrol (audio mixer), first check the configuration tab, to see
if the Built-in Audio is set up correctly. "Analog stereo duplex" is
probably right.
Then, on the "Input devices" tab, at the bottom set it to show
"Hardware Input Devices", then check that the Port is set to the
correct port. For me, "Line In" shows correctly if something is plugged
in or not. Make also sure the gain is set to 100%.
That said, I sometimes have problems recording LineIn with Audacity,
even though all seems OK. have not yet determined what the cause is.

Audacity can record audio, it uses an internal 32 bit floating point
format by default, which is the best IMHO.
It exports in a number of formats, for FLAC select the audio you want
to export, choose File->export_select_audio, choose the flac format in
the drop-down box near the right bottom. Change the file extension in
.flac. I use Audacity multiple times per week.

<pre>I just plugged in my UCA202, and the system (Mint 20.2 XFCE)
immediately recognized it. It shows up in the audio mixer (pavucontrol)
as an extra input device and extra output device, both as "PCM2902
Audio Codec Analog Stereo".

1) My Behringer UFO202 USB Audio interface has arrived.<br>
As a first and easy test I have connected it to a PC USB port, the
RCA IN L+R to RCA OUT on a Toshiba videoplayer playing an Audio
music CD, and third connected earphones to UFO202.<br>
<br>
2) Yes, I hear the playback sound in the earphones, however no sound
if I plugin the earphones to the normal rear PC backplane's Jack,
and no sound in the corresponding speakers. Correct so far? <br>
<br>
3) pavucontrol<br>

</font><font color="#000000">5) I am unsure how to practically
go from here to record the Audio music files.<br>
<br>
6) Pulse audio or Alsa, what's the difference and how to
select/set each of them?<br>
<br>
7) Record with Pulse Audio Volum control (pavucontrol),
Audacitty or possibly Gnome-sound-recorder?<br>
<br>
8) Which tab/buttons for input in Audiacity (possibly
tape/noise filters) - I could not find the PCM2902 input or
see any sound response here<br>
<br>
9) Would it be reasonable to record and archive in lossless
FLAC format and afterwards convert with ffmpeg? to smaller
files format of good quality, typical MP3 at 320 kbps (for
car usb player) and MP4A for home HiFi?<br>
<br>
10) Do you have command or gui procedures for these?<br>
<br>
<br>
Thanks<br>
