I knew it; I do a help -i for "play" and "sound", but not for "audio", so 
I didn't find playaudio. :-/

Well, I just used the source for playaudio, and it does the tmpfile
shuffle, but it basically cats the result to /dev/dsp (for a vector) or
/dev/audio (if possible, for a file).  There are, as JWE points out in the
source, some limits to this approach.

It would appear that SoX could be a better basis for this kind of thing
(better abstraction in general, much more flexible for playing and
encoding output files, works with Win32 stuff, would make it easier to be
more Matlab compatible).  And, it would be handy for me to have,
personally.

But, I suspect that there would be an issue with making SoX Yet
Another Dependency for building Octave.  If I got this working, does
anybody else think it would be worth it?  (You can send me email if you
want to spare the list...)
