It works...!!! That's what I did: 1) I plugged the Behringer into the mains; 2) I connected the Behringer to the PC via Behringer's USB cable; 3) I plugged 3 amplified loudspeaker (could also be not amplified but then sound is low) into 3 of the 4 black holes (the TRS ones, but it could be ok also with the RCA ones, I didn't try yet) of the `PLAYBACK OUTPUTS' system on the back of the Behringer; 4) from my Linux box I did: $ ecasound -f:16,3,44100 -i:sndfile,3canali.wav -o alsaplugin,2,0 where `3canali.wav' is a 3-channels file. And voilà: each of the 3 loudspeakers play a different channel of the 3 channels composing `3canali.wav'. There don't seem to be any issue with Behringer's controls: the `MAIN OUT' and `MIX' knobs can be whatever, such as the `STEREO/MONO' switch (so it seems). Thanks to each and all that helped...!
