Does this produce a click sound with other players on Windows? I
tested it with Winamp and it didn't.

OTOH, if you use a sound of 4 bytes or more, it works (in Emacs, and
also Winamp). So it seems like a limitation of Windows (or some
underdocumented feature of the .au file format),

I've also added a comment to play-sound's docstring. :device is not
supported, either.
