我试着通过kivy播放声音，但一直无法工作。释放按钮时，方法似乎运行成功（即print语句运行，应用程序没有崩溃，也没有错误消息出现），但没有声音播放。查看kivy数据记录器后，标题中的警告显示。

from kivy.app import App

from kivy.core.audio import SoundLoader
from kivy.uix.boxlayout import BoxLayout

class Play(BoxLayout):
    sound_done = SoundLoader.load('beep-01a.wav')
    sound_finishing = SoundLoader.load('beep-07.wav')

    def play_sound_1(self):
        self.sound_finishing.play()
        print ("sound 1")
    def play_sound_2(self):
        self.sound_done.play()
        print ("sound 2")

class Sound(App):
    def build(self):
        p=Play()
        #p.start()
        return p

if __name__ == "__main__":
    Sound().run()

千伏

        text: "sound 1"
        on_release:
            root.play_sound_1()
    Button:
        text: "sound 2"
        on_release:
            root.play_sound_2()

我试过使用wav，mp3和ogg的声音文件类型，但都没有工作。我已经坚持了很长一段时间，所以任何帮助将是非常感谢！谢谢
