Possibly a stupid question, did you start the processing with 'start'? :)
Anyways, you can use command "fs" (or aio-status) to view what files
are active and how they are connected. Also with this command you are able
to see the current position of each file. If these values are not changing
during processing, then something is wrong.
Test also the basic full-duplex functionality by issuing:
ecasound -i /dev/dsp -o /dev/dsp
.. you should hear what you are playing from the soundcard output.
PS Also try -b:256 or -b:1024 instead of -b:200...
