Oh, not to mention, you also have to make sure nothing else is using
/dev/dsp, e.g. no desktop system or alternative audio system. All in
all, the current Octave method for playing sound requires the planets
to be perfectly aligned up to 8 significant figures and we really need
something far more portable. Compatibility layers such as portaudio or
SDL seem like the possible options.
