I am using the 1810c for live sound at my church, and using the USB output to a PC for routing the sound to Zoom.
Simply put, the live sound works fine (all four inputs are routed to the speakers via Main Out) but I am unable to find a way to route the sound from all four mics into Zoom from Universal Control. Regardless of which output I choose in the Windows sound controls, I am only able to send audio from either Line 1/2 or Line 3/4 audio to Zoom.
Any help is greatly appreciated!
