Hi Daniel,
I just found some time to look at your problem, sorry for the delay.

Sure, the ContribLib is waiting for stuff like this. ;)

That's controlled by the pointerfieldtypes="..." variable. By default
it's "none", you can set it to "single", "multi" or "both", to generate
SFAudioClipPtr, MFAudioClipPtr or both. You need to rerun fcdEdit to
create the OSGAudioClipFields.h file.

See above.
Using fcdEdit should also get rid of the non-exported symbols for
Windows.
Hope it helps
