In the AudioReflectorDriver example, in AREngine::CreateControls, we can see this type of control being created
IOAudioSelectorControl::create(0, theChannelID, theChannelName, 0, kIOAudioSelectorControlSubTypeDestination, kIOAudioControlUsagePassThru);
What is the intended use of this control type? I cannot seem to see it in Audio MIDI Setup or elsewhere.
Can we present the user with a choice somehow based on this Control which would allow the Input to a virtual driver be passed to a real output?
I am looking to run effects on system-wide audio before sending to the output.
Thanks
Kevin
