Agreed. Haven't tried with sox (yet) but my previous attempts to demux mp3 audio from an avi file to wav via ffmpeg, piping the output directly to aften, resulted in aften closing immediately and a 0 byte AC3 file being produced.
Although I seem to recall reading somewhere recently that sox calculates the supposed output size and writes a valid wav header to a pipe, whereas ffmpeg does not, so some experimentation might be in order.
