Question / Help How to balance volume when having: Spotify + Zoom + Music band playing live


New Member
Hi guys,
I lead the music ministry in my church, so I need to do some facebook live streaming... I need to include the church service lead on Zoom, while I'm playing the music (connected to my laptop, using an audio interface - focusrite scarlett 2i2)...and before it all begins, I need to put a countdown timer with spotify music on the background.

I 'm an OBS newbie, but I was able to accomplish this.. HOWEVER, I'm having a hard time trying to keep the right balance on the volume, my room's speaker, etc. How can I make sure all the 3 audio inputs have exactly the same level?
