Default Output issues with MBox3 pro


All of a sudden I have lost input on my MBox 3 pro. When I go to the MBox control panel, the faders for outputs 1/2, 3/4 etc are all down and when I try to bring them up, they immediately return to the off position. I can't see where things have gone wrong. Working one minute, no output at all the next.

If someone knows where I have gone wrong, please point me in the right direction.

Have you tried a restart? Have you changed anything recently, installed or updated anything?

IIRC, Pro Tools takes exclusive control of the mbox driver when opened unless you untick the setting in the driver allowing this. If the faders won’t move, it’s because pro tools is open.
