I added it. Very recently. Sound for the secret zone in the new scenario (which I am currently working on); the sound plays, though a bit quietly.
The sound is taken from the game Quake and consists of the phrase "You found a secret area" spoken in a metallic voice. Format .wav.
I think I can help. What isn't working for you?
When attempting to play the sound, the console shows an error: Can't load the sound...
I don't understand what I did wrong.
