HUE Intuition supports multiple HUE cameras connected at the same time. The user can switch between them using the device dropdown in the bottom right corner of the screen.
As each HUE camera includes its own USB microphone, this would normally mean that you could switch between each microphone independently, just as you can with the video stream.
However, at this time macOS does not support multiple identical microphones. You will only see the first HUE microphone in HUE Intuition’s list of audio devices (along with any built-in or connected third party microphones). This is not a bug in HUE Intuition as the same issue occurs in Apple’s own apps such as QuickTime and Face Time.
If Apple releases a macOS update to support identical microphones, you will be able to switch between multiple HUE microphones in HUE Intuition as normal.
