Hi,
I've noticed that in Mac if when creating audiounit with VoiceProcessingIO it is ducking all the system audio.

Is there a way to avoid it?

This is how I create it:

Code Block     AudioComponentDescription ioUnitDescription;
    ioUnitDescription.componentType = kAudioUnitType_Output;
    ioUnitDescription.componentSubType = kAudioUnitSubType_VoiceProcessingIO;
    ioUnitDescription.componentManufacturer = kAudioUnitManufacturer_Apple;
    ioUnitDescription.componentFlags = 0;
    ioUnitDescription.componentFlagsMask = 0;
    AudioComponent outputComponent = AudioComponentFindNext(NULL, &ioUnitDescription);
    result = AudioComponentInstanceNew(outputComponent, &m_audioUnit);
