Hmm, what soundcard drivers are you using? One possibility is that you are
using OSS drivers that don't support multi-open style full-duplex
operation. In this case ecasound will hang when it tries to open the
second instance of /dev/dsp (one for reading, one for writing).

How about:

ecasound -a:1 -i foo.wav -o /dev/dsp0 -a:2 -i /dev/dsp1 -o bar.wav

... or try installing ALSA0.9.x.
