fifo pipe as input

Hi,

I want to use the output of mplayer as an input to ecasound. With a fifo I
can play it with aplay but have no idea how to get it to play in ecasound.
Anybody can tell me what I am doing wrong here. This works:

mkfifo /tmp/audio
mplayer  -vc null -vo null -af format=s16le -srate 44100 -ao
pcm:nowaveheader:file=/tmp/audio http://icecast.omroep.nl/radio1-bb-aac
aplay -t raw -c 2 -f S16_LE -r 44100 /tmp/audio

but replacing aplay with ecasound gives me this error:

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

thx!
