Welcome to the world of under baked software.
Thoughts - Be thankful you only jumped on board now, it was a real stinker when released.
Experience - Yes experienced this even after 2 updates, factory sounds are well '
non sounds' or "
VOID" of sound as you say.
They are apparently fixing this, and well they apparently '
fixed' this, as I think I recall correctly the release notes of one of the updates stated that all factory sounds were '
normalized' and they obviously are not, some you still can
juuuusssstttt hear if you listen closely, and others in comparison will perforate your ear drums (
slight exaggeration, but not so far from the truth) and that is after 2 updates and what 5 months on . For me it ended up not being worth the hassle and aggravation as there are many other top quality fully functioning and might I say just over all better (
not beta, which is what Rapture Pro is) options available which work as they should right out of the box.
