You can use a sub thread to complete audio playback, Then start the sub thread when playing the first frame of the video。
Like this:
PS：audio_devices['input'] and ‘output’ is device index of microphone and audio。

class PlayMusic(QThread):

wav = None
def __init__(self):
    super().__init__()
    self.setObjectName('play_music')
def run(self):
    wf = wave.open(self.wav, 'rb')
    p = pyaudio.PyAudio()
    audio_devices = get_audio_devices()
    stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                    channels=wf.getnchannels(),
                    rate=wf.getframerate(),
                    output_device_index=audio_devices['input'],
                    output=True)
    data = wf.readframes(chunk)
    input_stream = p.open(format=FORMAT,
                          channels=CHANNELS,
                          rate=RATE,
                          input=True,
                          input_device_index=audio_devices['output'],
                          frames_per_buffer=chunk)
    while len(data) > 0:
        stream.write(data)
        data = wf.readframes(chunk)
        data2 = input_stream.read(chunk)
    stream.stop_stream()
    stream.close()
    wf.close()
    p.terminate()
