I have a CQ-18T connected to my PC via USB. I have it configured for stereo stream mode at 48 khz. I’ve tried various Source Points. When I play something from the computer, I can see the levels on the USB input and hear it on the PA which I have connected to Aux 5-6. I have microphones set to output to LR Mains at unity. When I talk in the mics, I can see the levels on LR Mains and hear it on the PA. However, no audio appears on the mic input on the PC. I have tried audacity and zoom and nothing. I even tried this on Mac with same results. I’ve been through all the settings from top to bottom and I am not seeing anything to fix it. Any idea why I can receive audio from the computer but the computer is not seeing any audio from the mixer? I have tried multiple usb cables as well. Thanks!
