Switching audio input/output device #4
Comments

Since there is no API reference for Python at this point, please refer to Audio Device Manager and Video Device Manager which is similar. Besides, Here is a naive example: >>> import agorartc
>>> rtc = agorartc.createRtcEngineBridge()
>>> eventHandler = agorartc.RtcEngineEventHandlerBase()
>>> rtc.initEventHandler(eventHandler)
0 (Success)
>>> rtc.initialize("your-appID", None, agorartc.AREA_CODE_GLOB & 0xFFFFFFFF) # If you do not have an App ID, see Appendix (https://github.com/AgoraIO-Community/Agora-Python-SDK#appendix).
0 (Success)
>>> audio_recording_device_manager, err = rtc.createAudioRecordingDeviceManager()
>>> err
0 (Success)
>>> audio_recording_device_manager.getCount() # Obtain the number of microphones.
2 (There are 2 microphones)
>>> audio_recording_device_manager.getDevice(0, '', '') # Obtain device information of the 1st microphone.
[0, 'default (MacBook Pro Microphone)', '83'] ([ERROR_CODE, device_name, device_id])
>>> audio_recording_device_manager.getDevice(1, '', '') # Obtain device information of the 2nd microphone.
[0, 'HD Pro Webcam C920', '88'] ([ERROR_CODE, device_name, device_id])
>>> audio_recording_device_manager.setDevice('88') # Set the 2nd microphone as the recording device.
[0, '88'] ([ERROR_CODE, device_id])
>>> rtc.release() |

Thanks! |

Following this pattern, after calling import agorartc
RTC = agorartc.createRtcEngineBridge()
eventHandler = agorartc.RtcEngineEventHandlerBase()
RTC.initEventHandler(eventHandler)
RTC.initialize(Clubhouse.AGORA_KEY, None, agorartc.AREA_CODE_GLOB & 0xFFFFFFFE)
audio_recording_device_manager, err = RTC.createAudioRecordingDeviceManager()
audio_count = audio_recording_device_manager.getCount()
for i in range(0, audio_count):
if "VB-Cable" in audio_recording_device_manager.getDevice(i, '', ''):
print("Set Audio input to: {}".format(audio_recording_device_manager.getDevice(i, '', '')) )
print(audio_recording_device_manager.setDevice(audio_recording_device_manager.getDevice(i, '', '')[2]))The second part of the code simply uses the number from the test device as the input for setDevice. |

@shayanb By the way, a typo in your code: |

Thanks @YiqingJackieHuang . yes, as soon as it gets to the |

Hi, @shayanb. Please provide me with the crash report to find out the possible cause. The crash report can be found in Console app on macOS.

Hi, @shayanb. I find out that Python 3.9 causes the problem while it runs properly on Python 3.8. Would you mind using py38 instead? I am going to dig deeper into the problem. As soon as I find it out, I will notify you. |

Thanks @YiqingJackieHuang , it seems to be working on Python 3.8.6 now. |

Hi, I'm trying to understand how to switch input and output device using python sdk
I can get audioDeviceManager, but I don't understand how to set, i.e. input device using setDevice.
