Could you please test this code to see if the order of the ioctls is
right for FreeBSD? Just put a wav file (44.1kHz, stereo, little-endian)
named sai.wav on the same directory where you compile this and tell me
if it plays the file.
It was just a quick and dirty work, but I think that it would be a good
preliminary test.

Nice. Thanks.
