[Tutor] sound implementation problems

[Francois Dion]

I'd start with something simple first, to make sure you have sound output
etc. Run python interactively in the directory you have your wav file. At a
minimum, you need to import pygame, init the mixer (args are not really
needed, but I'll use what you had), set up the sound file and finally, play
it:

>>> import pygame
>>> pygame.mixer.init(22050,-16,2,4096)
>>> snd = pygame.mixer.Sound("bach-cello-suite-1.wav")
>>> music = snd.play()

music will start playing in the background. To check if the music is still
playing:

>>> music.get_busy()
1
>>> music.get_busy()
1
>>> music.get_busy()
0

And that's that. In your code, your run() function was probably a method
taken out of a class where sound returns a filename and seek(0) seeks to
the beginning of a file. You are missing the rest of the class. But, like I
said, you really only need 4 lines to play a wav file.

BTW, nice russian машинистка in the background image of your site.
