[ecasound] understanding loop device use

Hello,

I definitevely not understood how to use the loop devices, here is what
I want :

# ecasound chainsetup file

# general
-b:128 -r:-1 -z:intbuf -z:db,100000 -n:"test" -X -z:noxruns -z:nopsr
-z:mixmode,avg

# audio inputs
-a:1 -f:f32_le,2,48000 -i:jack
-a:2 -f:f32_le,2,48000 -i:jack
-a:3 -f:f32_le,2,48000 -i:"loop,1",1
-a:4 -f:f32_le,2,48000 -i:"loop,2",2
-a:5 -f:f32_le,2,48000 -i:"loop,1",1
-a:6 -f:f32_le,2,48000 -i:"loop,2",2

# audio outputs
-a:1 -f:f32_le,2,48000 -o:"loop,1",1
-a:2 -f:f32_le,2,48000 -o:"loop,2",2
-a:3,4,5,6 -f:f32_le,2,48000 -o:jack

and here is what ecasound tells :

dubphil@email-addr-hidden ~ $ ecasound -c -s test.ecs

ecasound: ERROR: [ECA-SESSION] : "Errors parsing session-level options. 
Unable to create session."
I believed I could give a chain an output loop device and use this loop 
as input for several other chains...
am I wrong ?

Philippe
