It's difficult to say with only that info. Have you tried the same file
on an x86 (with and without FIXED_POINT) and comparing the results. If
you still can't find the problem, please post the file somewhere (along
with the encoded version) and I'll have a look at it. Oh, and are you
using speexenc/speexdec or you own encoder and decoder?
