On OSX, we could get the `device name`, `unique id`, and `firmware version` by `kAudioObjectPropertyModelName`[0], `kAudioDevicePropertyModelUID`[1], and `kAudioObjectPropertyFirmwareVersion`[2]. It would be better if we also get the transport type(e.g. USB, HDMI, PCI, AirePlay, etc.). It could be accessed by `kAudioDevicePropertyTransportType`[3].
