Ecasound can correctly identify and open the audiofile in
both of your tests above, with and without libsndfile. You
can see it identifies the sample rate and channel count
correctly both times.
The problem is with the ALSA output. Something is wrong with
the soundcard device, its driver or its alsa interface via
alsahw,2,0.
You could try listing the sound devices.
aplay -L
Choose one you want and use -o alsa,DEVICENAME
You can also cat /proc/asound/cards.
Oh, and make sure you don't have pulseaudio running.
