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...!
