Mac Mic Stream only giving indata as 0's

See original GitHub issue

I am using a streamer like this

self.audio_streamer = sd.Stream(device=self.input_device, channels=self.channels,
                                        samplerate=self.sampling_rate, dtype='int16',
                                        callback=self.update_audio_feed, blocksize=self.audio_block_size,
                                        latency='low')



def update_audio_feed(self, indata, outdata, frames, time, status):
        print("update_audio_feed")
        if status:
            print(status, file=sys.stderr)

        print(indata)
        outdata.fill(0)


Output :

The indata is an array with 0's always from the callback.
update_audio_feed
[[0]
 [0]
 [0]
 ...
 [0]
 [0]
 [0]]

Sounddevice is detectingt the mic fine but not getting the signal :
Device Info: {'name': 'MacBook Pro Microphone', 'hostapi': 0, 'max_input_channels': 1, 'max_output_channels': 0, 'default_low_input_latency': 0.04852607709750567, 'default_low_output_latency': 0.01, 'default_high_input_latency': 0.05868480725623583, 'default_high_output_latency': 0.1, 'default_samplerate': 44100.0}
Sampling rate: 44100.0

Any ideas what is going on ? I checked that PortAudio is installed fine …

I’m not a macOS user myself, but I’ve heard about problems with the microphone permissions on macOS.

Maybe this helps: https://www.reddit.com/r/MacOS/comments/9lwyz0/mojave_not_privacy_settings_blocking_all_mic/
