ecasound's riff-wave input (both with sndfile and without) requires to 
have a proper RIFF header, and this is not possible with piping. You 
should be able to use a RAW input though:

$ ecasound -D -z:nodb -f 16,2,44100 -i:typeselect,raw,/tmp/audio,wav -o alsahw,0,0

You'll just need to be sure the format is set correctly (-f:16,2,44100) in 
this case as there's no header to parse (and thus no negoatiation with 
mplayer).
