44 bytes is the size of the wav header, so parecord gets no data at all
from pulseaudio. Does plain alsa work either? Try

        pasuspender -- arecord -Dplughw:1,0 -f dat > test.wav

If that doesn't work either, then it's definitely not a pulseaudio
problem. If it works, however, then there's some problem related to how
pulseaudio uses the device. I don't have any ideas what that might be,
perhaps the pulseaudio log would have some clues. Instructions for
getting the log are here: https://wiki.ubuntu.com/PulseAudio/Log
