I havd an iBook running Debian and MacOSX and I have no problem so I should
be able to help you :-).

I've just tried SoX on both a 16 bit WAV and a 16 bit AIFF file and they
worked as expected.
What kernel version are you running? I'm using the benh PPC kernels
(2.4.19-rc1-ben0) available here:
These have some extra hacks which haven't made it into the manistream
kernel yet. One of these hacks I think is to fix the problem you are
having. I seem to remember that I only had 8 bit audio when I used
the Linux kernel (2.4.18).
Hope this helps,
Erik
