Problem trying to play sounds with pygame module

Question

I'm trying to play multiple sounds at the same time using pygame.
I'm using the function pygame.mixer.Channel(num).play(sound_path) but it gives me error!

IN THIS CASE:
import pygame
pygame.mixer.init(channels=10)
pygame.mixer.Channel(3).play("sound.mp3")

It stops giving me "TypeError: argument 1 must be Sound, not str"
So I've looked for a solution online and I found that I have to use the function pygame.mixer.Sound(sound_path) like this:

import pygame
pygame.mixer.init(channels=10)
pygame.mixer.Channel(3).play(pygame.mixer.Sound("sound.mp3"))

Running that I receive "pygame.error: Unable to open file 'sound.mp3'"
I don't know what to do, so I'm asking here!

Thanks in advice :))

EDIT: I've tried to convert .mp3 in .ogg: It doesn't give me errors but It doesn't play the sound too :((

Answer 1

i found this in pygame documentation

All sound playback is mixed in background threads. When you begin to play a Sound object, it will return immediately while the sound continues to play.

so its probably the program already closed, before the music is playing.

also from documentation mp3 format can have a problem ondifferent system.

Answer 2

Thanks mannn, It works! I've inserted a delay to let sound play, and It goes right! Now I'll finish my function, and I'll go back in case of obstacles. :)))
