Doubt about audioDeviceIOCallback and DeviceManager

Hi, it’s me with maybe another silly question…

I would like to know how I can send the input data from a new juce::AudioDeviceManager to an audioDeviceIOCallback. if you could provide me with an example Code, I would be very grateful; also, how can I return this data sent to another juce::AudioDeviceManager fully and in real time.

Thank you very much!

I think this is what is happening here: Using different audio devices at the same time? - #6 by Rincewind
