Stream with global audio source from PC (suppress any webcam audio)

Planning youtube live streaming projects. This is win10 workstation. Want to run 4 incoming webcam video feeds. And One live master audio mix from my DAW software (one of the computer’s audio device outputs). How do I select the 4 webcams as video sources, and NOT take any audio from those streams? I just want my master audio mix to supply the stream.

Is it possible? if so, then how? don’t see this on the website docs anywhere…


In the Audio tab there is a item called Audio Preset, where you can turn on and off the audio for each preset. Then add a new audio input for the DAW output.
