What setup or plugin settings have you tried? What error reports are being given?
I do not understand what you mean by does not work as is.
I did everything as shown in the video, but the sound doesn't work. The sound is played in the editor, but not in the game. I saw a comment there with the same problem, but when I tried to do what he was advised, it didn't work for me.
After the text is fully displayed, does the sound play? Does the set sound play at any given point of time?
