With ALSA 0.5.x, you always have to open the audio device in 10ch mode. So
always put "-f:32,10,44100 -i:alsa,1,0". To record a 10ch wav file:

ecasound -f:32,10,44100 -i:alsa,1,0 -f:32,10,44100 -o:10ch-file.wav

Putting channels in separate files is a bit tricky, but can be done.
For instance, copying 9ch and 10ch to a 16bit stereo wav file:

ecasound -f:32,10,44100 -i:10ch-file.wav -erc:9,1 -erc:10,2 -f:16,2,44100 -o:stereo-file.wav

No, but 0.6.x will (eventually) make things easier.
