Now, i have a couple of theories on this problem:
1. I have to progress even further to obtain these items for create mode (im on ziggurat with only 1 marble retrieved)
2. I plan on importing all my data from lbp1 and 2 once i feel like im done with the whole game, so therefore probably resulting in new players only getting those 3 default sounds? (highly unlikely, that would be a bad move Sumo...)
3. Maybe the bug i had last time (not receiving end-level objects) just impacts objects like sounds and materials too, so this is probably the the reason (highly likely)
4. Maybe the new patch will give us ALL the sounds

I also keep hearing DLC transfer problems, so ill hold off until sumo patches to bring everything in

If you can help me with these dear confusions, that would be great!

It is confirmed that the next patch of the game, 1.13 i think, will not only fix most, or hopefully all of the dlc problems. But also add all the sounds that are missing.

soooo many sounds missing . if you really don't want to wait for the patch. I believe it's possible to import them into lbp3 from lbp2
