Pygame, sounds don't play

问题:

I'm trying to play sound files (.wav) with pygame but when I start it I never hear anything.
This is the code:

import pygame

pygame.init()
pygame.mixer.init()
sounda= pygame.mixer.Sound("desert_rustle.wav")

sounda.play()

I also tried using channels but the result is the same

回答1:

Your code plays desert_rustle.wav quite fine on my machine (Mac OSX 10.5, Python 2.6.4, pygame 1.9.1). What OS and Python and pygame releases are you using? Can you hear the .wav OK by other means (e.g. open on a Mac's terminal or start on a Windows console followed by the filename/path to the .wav file) to guarante the file is not damaged? It's hard to debug your specific problem (which is not with the code you give) without being able to reproduce it and without having all of these crucial details.

For me (on Windows 7, Python 2.7, PyGame 1.9) I actually have to remove the pygame.init() call to make it work or if the pygame.init() stays to create at least a screen in pygame.

My example:

import time, sys
from pygame import mixer

# pygame.init()
mixer.init()

sound = mixer.Sound(sys.argv[1])
sound.play()

time.sleep(5)

I had no sound from playing mixer.Sound, but it started to work after i created the window, this is a minimal example, just change your filename, run and press UP key to play:

WAVFILE = 'tom14.wav'
import pygame
from pygame import *
import sys

mixer.pre_init(frequency=44100, size=-16, channels=2, buffer=4096)
pygame.init()
print pygame.mixer.get_init() 
screen=pygame.display.set_mode((400,400),0,32) 

while True:
    for event in pygame.event.get():
        if event.type == QUIT:                                                    
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            if event.key==K_ESCAPE:
                 pygame.quit()
                 sys.exit()
            elif event.key==K_UP:
                s = pygame.mixer.Sound(WAVFILE)
                ch = s.play()
                while ch.get_busy():
                    pygame.time.delay(100)
    pygame.display.update()

回答4:

sounda.play() returns an object which is necessary for playing the sound. With it you can also find out if the sound is still playing:

channela = sounda.play()
while channela.get_busy():
   pygame.time.delay(100)

回答5:

I had the same problem under windows 7. In my case I wasn't running the code as Administrator. Don't ask me why, but opening a command line as administrator fixed it for me.

回答6:

What you need to do is something like this:

 import pygame
 import time

 pygame.init()
 pygame.mixer.init()
 sounda= pygame.mixer.Sound("desert_rustle.wav")

 sounda.play()
 time.sleep (20)

The reason I told the program to sleep is because I wanted a way to keep it running without typing lots of code. I had the same problem and the sound didn't play because the program closed immediately after trying to play the music.

In case you want the program to actually do something just type all the necessary code but make sure it will last long enough for the sound to fully play.

回答7:

I think what you need is pygame.mixer.music:

import pygame.mixer
from time import sleep
pygame.mixer.init()
pygame.mixer.music.load(open("\windows\media\chimes.wav","rb"))
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
    sleep(1)
print "done"

回答8:

Just try:

import pygame.mixer
from time import sleep
pygame.mixer.init()
pygame.mixer.music.load(open("\windows\media\chimes.wav","rb"))
print ""
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
sleep(1)
print "done"

This should work. You just need to add print ""and the sound will have had time to load its self.

回答9:

import pygame, time


pygame.mixer.init()
pygame.init()

sounda= pygame.mixer.Sound("beep.wav")

sounda.play()

pygame.init() goes after mixer.init(). It worked for me.

回答10:

Just try to re-save your wav file to make sure its frequency info. Or you can record a sound to make sure its frequency,bits,size and channels.(I use this method to solve this problem)

回答11:

I've had something like this happen. Maybe you have the same problem? Try using an absolute path:

import pygame

pygame.init()
pygame.mixer.init()
sounda= pygame.mixer.Sound("/absolute_path/desert_rustle.wav")

sounda.play()

Where abslute_path is obviously replaced with your actual absolute path ;)

good luck.

回答12:

import pygame

pygame.init()
sound = pygame.mixer.Sound("desert_rustle.wav")
pygame.mixer.Sound.play(sound)

This will work on python 3

5 years late answer but I hope I can help someone.. :-)

Firstly, you dont need the "pygame.init()"-line. Secondly, make a loop and play the sound inside that, or else pygame.mixer will start, and stop playing again immediately.

I got this code to work fine on my Raspberry pi with Raspbian OS. Note that I used a while-loop that continues to loop the sound forver.

import pygame.mixer

pygame.mixer.init()
sounda = pygame.mixer.Sound("desert_rustle.wav")

while True:
    sounda.play()
