But if a device has input and output channels (like the Apple Thunderbolt Display) and sound is played back by that device, Core Audio reports the device as being active, but Micro Snitch can’t know if its input or the output is active. If a device only has input channels (as your Mac’s built-in microphone does) and it is active, Micro Snitch knows that some app is using the microphone. To go into a little more technical detail: Core Audio and Core Media IO (the macOS technologies apps use to interface with audio and video hardware) provide information on whether a device is active, but not on whether a device’s input or output channels are active. If such a device is connected, Micro Snitch will notify you about it and will not report any of that device’s activity.
