Hmmm, I have no idea what might be the problem. The only thing I did not
test with pd-l2ork is ffado interfaces. Perhaps you need to specify
different number of channels if your ffado device has them? I remember
encountering problem like it many years ago but i also suspect this has
been fixed since...
