Duplicate `start()` method in `audio_grabber.py` causes overriding logic error

[Jiya873]

While working with audio_grabber.py, I noticed that the AudioGrabber class defines the start() method twice.

The second definition overrides the first one, which prevents the original thread initialization logic from ever executing.

I am talking about this part:

Class AudioGrabber:
    def start(self):
        self.send_thread = threading.Thread(target=self.send_audio)
        self.send_thread.start()
 ... 

    def start(self):
        self.stream.start_stream()

I think this is an unintended behavior and could cause confusion to understand the audio sending flow.
