I don't know of any other software that plays non-mac sound format
without a conversion step first. I can't even imagine how they could.

There's quite a few programs at sumex-aim.stanford.edu:/info-mac/sound/
which read and write various sound formats, including ulaw, aiff, etc.
Maybe source code for some of those are available to inspire you...
