Great, at last someone creates a sound pack
I did not play with it yet.
I see that your config lists "elpurideath.wav", but I don't see this file.
The system also supports adding music (which can depend on current location).
No idea for sound packs, you could try to use sounds from other free games (but I think it is not always OK to do without authors' permission), or from sites called "free sound effects" or something like that.
