Yes, thanks...  Something is wrong with the device: the test with Audacity is
negative.  Besides, today I got a new USB audio card, that I bought in internet
when I saw that the first one wouldn't work: here it is:


I bought it because it was claimed to be working with Linux.  And in fact, it
works perfectly, also with the test you suggested with pavucontrol, and also
with this test in Audacity, and it records fine.  But maybe, it is simply that
the first one is defective...

Thank you indeed, Curt, for your help...  Thanks to all.
