Thanks: my main problem was the multichannel structure, not the conversion
itself.  Reading the manual as you suggest, I did:

 $ pacat --record -d alsa_input.usb-BEHRINGER_UMC404HD_192k-00.analog-surround-40 --channels=4 --channel-map=aux0,aux1,aux2,aux3 --file-format=wav dump.wav

and pacat performs the record but complains:

 Warning: failed to write channel map to file.

and in fact the resulting file seems not to be as accurate as the one I get
creating first the raw file and then converting it to wav via sox.

Thanks for your help,
