Input signal meter

It worked fine until last night.

I can hear the input and signal shows on main output bus, but no signal shows on the input meter or chael fader, and there nothing but silence when I try to record on a track. Restarted all hardware and software, no change. All software and drivers are up to date, ruing on new MBP and digi003rack.

Very frustrating "tech" issue in middle of creative flow. Waaa!
