I recently sent my Mbox3 for repairs due to hardware failure. after waiting a month I got it back it worked for one day....Now whenever I arm an audio track for a Mic or Instrument it produces no activity signal on the meter and only picks up vibrations if you tap the mic, and even that sounds distant and distorted. If I import an audio track into protools12 it does generate a signal on the meter, and the master meter. I have reinstalled the drivers, changed all cables and ports, but have had no luck. You can imagine how frustrating this is considering it just came back from repairs. Does anyone have a solution or similar problem?
