MBox 2 Pro Monitor knob has stopped changing monitor levels
 

Hi - I've developed a weird problem with my MBox 2 Pro: the monitor level knob no longer changes monitor levels, which are now fixed at the same level regardless of knob position.

I've so far tried reinstalling the driver, which hasn't changed anything. Also, the headphone level controls are both working as they should.

Could there be some setup option in PT I've missed, or some software setting I'm not aware of that I need to change? If not, does anyone have idea what could be causing this?

Thanks a lot for reading - any help much appreciated.

Problem solved! Which is good, but embarassing: MBox had been borrowed and put back with the monitor cables in the line out sockets (that'll teach me not to double-check!).

Sorry for anyone's wasted time.
