title: tkinter methods .bell() no sound
body: <p>I tried tkinter <code>.bell()</code> method but there was no sound. Below is a simple test code that I had used, it did not yield any bell sound. How to get the bell to work? </p>
  
  <pre><code>import tkinter as tk
  
  root = tk.Tk()
  frame = tk.Frame( root )
  label = tk.Label( frame , text='Testing w.bell() method')
  
  frame.pack()
  label.pack()
  
  label.bell()
  frame.bell()
  root.bell()
  
  root.mainloop()
  </code></pre>
  
  <p><strong>Update:</strong></p>
  
  <pre><code>$ xset q | grep bell
    bell percent:  50    bell pitch:  400    bell duration:  100
  </code></pre>
  
  <p>I can't understand why my system does not yield any bell sound despite others stating that they can here the bell sound.</p>
