I can't say I'm all that surpised, this is not something that was
designed to work.
That leaves you two options:
a) Debug the problem, come up with a fix and send a patch.
b) Work around it.

The problem you face is difficult enough with file formats that are
supported natively by libsndfile. It will be much more difficult for
the formats that require external libraries because the fix may
require fixes in libFLAC, libogg or libvorbis.
