I do not use ecasound but it seems to me that this indicates that by 
default ecasound is in a one channel (mono, channel #1) mode and that 
channels have to be specified with -a, perhaps like this:

$ ecasound -a:1,2,3 -i:sndfile,3canali.wav -o alsahw,2,0
 or perhaps
$ ecasound -a:all -i:sndfile,3canali.wav -o alsahw,2,0
