python - 为什么使用 winsound 和 tkinter 的 stop_sound 功能不起作用？

Question

from tkinter import *
import winsound
from winsound import PlaySound, SND_FILENAME, SND_LOOP, SND_ASYNC
root = Tk()
root.configure(background='light green')

def playing():
    PlaySound('alarm', SND_FILENAME)

def stop_sound(): 
    PlaySound(None, SND_FILENAME)

Button(root,text="playing ",font=("Helvetica 15"),command=playing).pack(pady=20)
Button(root,text="Stop",font=("Helvetica 15"),command=stop_sound).pack(pady=20)

root.mainloop()
