Go to the folder BrazilianCroft- Ship Graveyard/Sound/Samples. 

copy ALL the TR3 sounds samples to the original paste of samples in Tomb Raider Level Editor directory .

Later, go to Core Design/trle (you original directory of tomb raider level editor) /sound/level sfx Creator

then execute "SFX_Example.bat" and later "pcwadsfx.exe".

Now, all the sounds in the game are working correctly.

THANKS !
