I use the command:
to trigger the talk animation and play a speech sound. I show the dialogue text in a separate window, which is why I send an empty string.
When I run the game in debug mode, the speech sound plays fine. When I compile the game and run it from "packages" folder, the speech sound is not heard. I believe it is not an issue with sound effects volume, because other sound effects are heard fine.
Any ideas why this might happen?
