Problem with playing sound on pickup! Please help!

[Your Computer]

When the game is confronted with two or more files that bear the same name, it picks the first one it finds and ignores the rest. So, there is no need to provide the directory path of the file.

As for debugging sounds, there's an option in the debug menu that you can enable that has the game list all sounds being played at the upper left of the screen. Enable that feature, test the story again, and see if it is listed there.
