Hi Ben,

I halfway understand the reasoning but I don't really agree with it.
I don't see any significant problem with doing the byte swapping in
the kernel.  From an engineering standpoint, it seems to make more
sense to me to do this common function once in the kernel driver rather
than redoing it over and over in every audio app, and keep getting bit
by the same endianness problem over and over again.  Linus and the PC
world don't have to worry about it, but us PPC types keep getting a
delay in usable audio apps as a result.

Oh well, I know I'm tilting at windmills here.  :-)
