在多客户端语音聊天Python程序中没有向客户端发送音频 我想做什么

我正在尝试用Python创建一个多客户端语音聊天程序，客户端可以通过麦克风进行通信。我让它与TCP套接字一起工作，客户端将启动与服务器的连接，并将添加到列表中，然后在其中接收音频。由于性能原因，我尝试使用UDP套接字来实现这一点。事实证明，这很困难

预期和实际结果 当程序运行时，服务器等待客户机发送“连接”字符串，然后将该客户机的地址添加到列表中，启动一个线程从中接收音频，并将音频广播到所有连接的客户机。然而，发生的情况是，客户端似乎没有从服务器接收任何音频。当混音器拾取输入时，代码的音频部分似乎很好，但是没有接收到输出

错误消息 没有

代码 server.py client.py 有谁能提出一些建议来解释为什么这个代码不起作用？ 谢谢
