Pygame - Sound delay

Question

I\'ve made a button class that checks if a button is selected (when the mouse is hovering over the button). When the button is selected, unselected or clicked it plays a wav

Answer 1

Simply decreasing the size of the buffer, as often suggested for this problem, did not work for me. I found this solution. When initiating the mixer twice, the delay completely disappeared:

import pygame

pygame.mixer.pre_init(22050, -16, 2, 1024)
pygame.init()
pygame.mixer.quit()
pygame.mixer.init(22050, -16, 2, 1024)

It's a bit dirty and I don't know why it works, but hopefully it solves the problem for some people.

Tested on Ubuntu 16.04 LTS with Python 3.6 and pygame 1.9.4
