更新：我在pygame中使用了不同的声音功能来尝试进行故障排除。这是我的新计划。
#pygame mixer testing
import pygame
pygame.init()
sound = pygame.mixer.music.load("jan_amit.wav")
这是错误。
Traceback (most recent call last):
File "C:\Users\Will\Desktop\Programming\Python\Programs\shmup\snd\pygame mixer testing.py", line 5, in <module>
pygame.mixer.music.load("jan_amit.wav")
pygame.error: Unknown WAVE data format
如何更改wav数据格式？
（旧帖子）---我是初学者，我正在尝试学习如何使用pygame。但是，当我尝试使用pygame.mixer.Sound()将声音加载到我的游戏中时，我收到此错误：
C:\Users\Will\Desktop\Programming\Python\Programs\shmup\snd\bullet_shoot.wav
Traceback (most recent call last):
File "C:\Users\Will\Desktop\Programming\Python\Programs\shmup\shmup.py", line 127, in <module>
shoot_sound = pygame.mixer.Sound(path.join(snd_dir,"bullet_shoot.wav"))
pygame.error: Unable to open file 'C:\\Users\\Will\\Desktop\\Programming\\Python\\Programs\\shmup\\snd\\bullet_shoot.wav'
[Finished in 6.5s]
看来这个pygame函数不知何故在每个其他反斜杠旁边插入一个额外的反斜杠。所以为了排除故障，我打印出了我正在输入功能的字符串。果然，单反斜杠。
C:\Users\Will\Desktop\Programming\Python\Programs\shmup\snd\bullet_shoot.wav
这是完整的代码，因为我不确定发生了什么。
