Do you think, e.g., the Behringer > UMC404HD audio interface will allow to do that? 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...?
