As a live mixer running my hardware synths, everything works fine. When I switch to DAW mode, though, it's clear that the mixer and software (Studio One Pro 4.5) are communicating; sliders move, meters show input, etc. However, nothing comes out of the speakers. Even the main output's meters show action...just nothing is heard. PLUS, it is very noisy. Turn off DAW mode, though, and I'm right back to normal...synths can be heard through mixer and speakers. Any idea what's up? By the way, I've updated all software and firmware.
