Hi everyone.

I bought the Behringer UMC404HD and plugged three loudspeakers into the
`Playback Outputs' set on the back of it. Then I did:

 $ ecasound -a:1,2,3 -i:sndfile,3canali.wav -o alsaplugin,2,0

where `3canali.wav' is a 3-channels file. The above command properly sends
channel 1 into speaker 1 and channel 2 into speaker 2, but does not manage to
send channel 3 into speaker 3. Actually, the output set on the back of the
Behringer seems to behave in stereo mode rather than as 4 single independent
outputs. (Moreover, the `B' part of that output set - i.e. 3 and 4 - do not
seem to be active at all and look like dead.) I begin to believe and be afraid
that what I want is not technically possible at least with that piece of
hardware. Please help on this issue you experts out there: is it possible and
how to do what I want, and is it possible at all with an audio interface as my
Behringer either with some other device...?

Thanks for any help,

Rodolfo
