Find out what characteristics this device has (supported sampling rates, channels etc.).Check if there is USB microphone connected to the device.To use third-party libraries is overkill for me since I need to only receive the stream of audio data from the microphone, the rest of the processing is already done and working, only the audio source is the issue. What I need is to use the USB audio feature but so far I am unable to make any progress. I have tried to use the MediaCapture with as source which worked but recording quality isn't quite usable for me and you can't be sure if the audio source is really USB or the built in device microphone. I am struggling on how to capture the audio stream from connected USB microphone.
