This may just be because the 16bit sound files are bigger...

I think I heard somewhere that the PPC /dev/dsp uses little endian format,
while Sparc uses its native (big) endianness.

If someone could give me a table of what endianness the sound devices on
various platforms expect, I could make an esound-0.2.15 that fixes it
(after having you all test it :).

The first thing a programmer needs to admit is that any program is by far
more complex than his own mind. Thats why he partitions it into neat
pieces and avoids complexity.
