Can you try manually swapping the bytes on the raw output and see if you
get something useful (I think by default wav is always little endian
while raw is native endian)?

One of the reasons is that with 1.1.x, I introduced a fixed-point
(integer) port and I wanted to have the same API for the float and the
fixed-point version. The other reason is that it makes it harder for
people to screw up the scaling.
