Need help to use sound board

Hello all!
So I just purchased the stream deck and would like to add a sound board to it. My question is what do I need to do so that my viewers can hear the sound but as well as the players in my game through my headset mic.

I am on pc and currently stream using streamlabs obs to twitch. I play my game on pc as well and the sound of the game gets recorded through display capture.

Any help would be much appreciated, I’m new to all this so if anyone can simplify it for me that would be great!lol thank you

It’s a great bit of kit! Here’s a video showing basic soundboard features of the Elgato Stream Deck:

If you’d like viewers and game players to hear it you’ll either need a mixer of a software solution like Loopback (for Mac) or VoiceMeeter Banana (for PC)
