I also have a SuSE 9.2/x86_64 (dual Opteron) system and did run
into a few problems with WAV files. The problem was that 'long'
was used in a few places in the code which dealt with WAV files.
On a IA32 system that's 4 bytes but on a x86_64 system 'long' is
8 bytes and the result was invalid/corrupt wav files.
That has since been fixed in the CVS version.

It may (or may not ;)) be your problem but I know there were a few
places that needed to have 'long' changed to 'int32_t'. There is
a chance that you're seeing the 64bit vs 32bit "sizeof long" problem.
If the problem still occurs with the cvs version then there are
remaining problems to be fixed but I think the cvs version's in
pretty good shape (just can't seem to get a release going ;)).
