Before upgrading to the Quantum 2626, I used a Audient ID14 as my Audio Interface. Instead of juggling the USB cable between using my PC or MacBook Pro, I am trying to monitor the sound from my MacBook Pro as an input to any channel on the Quantum, being that it is then routed to my StudioLive AR12 mixer which connected to my Studio Monitors.
Also, I'm trying to use the audio out from my PC sound card to the Quantum and I'm having the same issue. The input LED shows a signal but no sound.
