Trying to play sound. Getting fatal error.

[metulburr]

Mixer pre init goes before pygame.init()

pygame.mixer.pre_init(frequency=44100)
pygame.init()

And you run pygame.init() only ever once
Remove lines 2 3 5 and 8. Move line 6 to line 3

If you still have an issue after that try a completely different sound file to test. Dont convert anything.
