Live Stream Meditation to an Event and Online at Same time

[liveinflow]

I have beens struggling for years to untangle this issue.  Would love any insight.  We have a facilitator that is streaming in via zoom.  We are able to put the video on a projector and send her voice from zoom into the mixing board and out to the speakers in the venue where we are holding the workshop.  We also have online participants who are getting on the same zoom call with the facilitator to participate remotely.  This is all good.  The issue arises when the facilitator leads a meditation/yoga session and we share music to the zoom call as well as play the music in the venue for the in-person participants.  Because the best and cleanest way to get sound into the zoom call is doing an advanced screen share "computer audio only". what this does is creates a virtual sound output 'zoom audio device'. the problem occurs because this device merges the computer output with the virtual output in the zoom call.  Meaning the voice of our facilitator gets merged with the audio that is being streamed from spotify on the same computer.  Aside from multiple computers is there a way to untangle the audio streaming to the computer output and the audio coming out of zoom?
