How to use python client with microphone？

[YAETHeryk]

I deploy the service using Docker and test the sample client on my local machine. The problem now is that I test the HTML page, record with my microphone, and it works correctly. Then I test the Python client using a WAV file, and the result is also correct.
However, I continue to test the microphone mode of the Python client with command:
python funasr_wss_client.py --host "0.0.0.0" --port 10095 --mode offline
the client only shows:

Namespace(host='*******', port=10095, chunk_size=[5, 10, 5], chunk_interval=10, hotword='', audio_in=None, audio_fs=16000, send_without_sleep=True, thread_num=1, words_max_print=10000, output_dir='./results', ssl=1, use_itn=1, mode='offline')
Namespace(host='*******', port=10095, chunk_size=[5, 10, 5], chunk_interval=10, hotword='', audio_in=None, audio_fs=16000, send_without_sleep=True, thread_num=1, words_max_print=10000, output_dir='./results', ssl=1, use_itn=1, mode='offline')
connect to wss://*******:10095

No output, despite occupying the microphone.
I'm not sure if any steps or operations were missed.
