How have you created the file? The trace message seems to indicate the
file does not have the common PCM file header (maybe it's in w64 format,
or something similar).

Anyways, the cure is easy and that's to use libsndfile for RIFF WAVE
parsing. I.e.:

sh> ecasound -a:1 -i:sndfile,mixed.wav -o:jack,system

If you have have libsndfile utils installed, you can get some additional
info about the file with:

sh> sndfile-info mixed.wav
