I have a firebox, VCI-100, vdj 6, and a macbook. For the life of me I cannot get the microphone to work. When I change system preferences on the macbook I can see a signal coming from the mic. When I turn the mic knob up all the way and shout into the mic I can see that its clipping but no sound comes out at all. Is there something that im doing wrong in the firebox mixer settings?

thanks
