I suppose I would listen to audio from my Debian box, connecting it to a sound
interface as Behringer or similar.  Or also maybe to some 5.1 audio card?

Some years ago on debian.user mailing list it was suggested that "ecasound" can
do that, with ALSA:

 $ ecasound -i:3ch.wav -f:16,3,44100 -o:alsa,default

Now I wish to be sure Behringer UMC404HD will allow me to do that before I
purchase it.  It is claimed to have 4 outputs, but its output system looks
quite complicated: on the back of the device it shows `PLAYBACK OUTPUTS': two
white, two red and four black outputs.  Further on the right, one more couple
of black entries, L and R, and then MAIN OUT.  How could I use all those to
achieve what I'm looking for?
