How to identify audio device type when screen recording with Expression Encoder SDK

Question

Hello.

According to screen recording sample of Expression Encoder SDK, "EncoderDevices.FindDevices(EncoderDeviceType.Audio)" returns all avaiable audio input devices.

However, the returned collection contains both microphones and system audio.

How can I identify whether a audio device in the collection is microphone or system audio exactly?

(Of course, device name can be used, but sometimes it is hard to identify device type by its name. So, I think that it is not a good solution.)

Best regards.
