And some additional information on the problem:
while trying multitrack recording with
# ecasound -d:255 \
-a:1 -i janet_drums.wav -o /dev/dsp \
-a:2 -i /dev/dsp -o hei.wav
the following appears on screen before it hangs:

i.e. the chain a:1 seems to do well, but everything which happens with
chain a:2 is those "Set buffer size"-stuffs on the last two rows and then
... nothing. The attempted multitrack recording does not succeed and I
have to press Ctrl-C to exit.
