The Linux audio programming docs do clearly state:

linuxaudiodev.c does this:
ioctl(self->x_fd, SOUND_PCM_WRITE_RATE, &rate)
ioctl(self->x_fd, SNDCTL_DSP_SAMPLESIZE, &ssize)
ioctl(self->x_fd, SNDCTL_DSP_STEREO, &stereo)
ioctl(self->x_fd, SNDCTL_DSP_SETFMT, &audio_types[n].a_fmt)
which is exactly the reverse order of what is recommended!
Alas, even after fixing this, I *still* can't get linuxaudiodev to
play the damned .au file. It works fine for the .wav formats.
I'll continue hacking on this as time permits.
