I have the feeling you posted a different command than you actually ran.
It's best to copy and paste exactly what you did so we know exactly what
you ran.

This should work...

ecasound \
-a:1,2 -f:24,2,44100 -i jack,system \
-a:1 -f:24,1,44100 -o:foo1.wav \
-a:2 -o:foo2.wav \
-a:2 -chmove:2,1

You can put all the commands in a text file (without all the '\'). Then
run it like this...

ecasound -s:/path/to/file.ecs

This way, you can make changes... run it... make changes... run it...

If you run ecasound in 'interactive mode', you can issue commands in the
same shell you ran ecasound in...

ecasound -c -s:/PathTo/file.ecs

If you want to see a well formated 'ECS File'... while in interactive
mode, issue the command cs-save-as /PathTo/NameOfFile.ecs

...or just cs-save, to update the file you're currently working with.
