This is an extremely simple mod whose function is to play a notification sound when you first launch the game and enter the main menu, and it has been open-sourced on GitHub.
The default notification sound is the Windows XP startup sound. If you are not satisfied with the default sound, you can modify the notification sound by changing the st-sound.wav file located in the config directory of the game directory.
