Audio From OBS to Zoom

[holsen]

Hi, I'm new here and have figured out to to broadcast multiple sources and scenes from OBS into zoom. I held a very successful training session today with countdowns, PowerPoint and and me Chroma Keyed into the lower corner of the display with The Slide show running in a window capture. It was beautiful BUT
for the life of me, I cant figure out how to get audio in videos playing in OBS to send over to the Zoom.
I'm hoping someone here can help me.
My Set Up

• External Mic into USB Audio Interface
• Speakers - USB Interface

So in Zoom, I have my mic set up as Interface and Speakers set up as Interface with Camera set as OBS virtual. In today's session everything worked fine, except the audio from a Video I was trying to play as a Scene / source. The video played, and everyone on the zoom meeting could see it but there was no audio playback. I ended up deleting the scene and opening the video in a separate window and doing a screen share in zoom for that portion. Can someone tell me how to get the audio in a video in OBS to be picked up in Zoom?
