So a friend of mine had the briliant idea that we need to stream and comment the play off games in our BB2 Leauge.

I managed to set up everything with OBS so it can stream to twich - but there is one issue I can't figure out how to solve:

Since it will be two of us commentating we need both of our voices, but If we use discord in the browser and it outputs to "default" the audio gets picked up with game audio meaning I can't easily control gain/level, etc for just his voice.

I though I was clever by sending the output of discord to a (usb) output device that doesn't actually have anything connected to it. This lets me get the audio on a separate channel in OBS - slight issue though *I* can no longer hear it xD this ofc makes communication a tad harder

So how do people do it? Right now I'm thinking it involves using JACKS to setup a virtual devices that can be captured individually that are then combined into the real output.. but last I used JACKS it involved some hardcore text editing in both jacks and alsa files.

So I'm hoping there is an easier way to achive my goal.

Bonus questions:
- since window capturing doesn't work for me, I guess there is no way to get his webcam as a source in OBS?
- how do you install plugins in the flathub version of OBS, I wanted a virtual greenscreen addon but it seems I need to manually compile it and install it in a non standard folder?

System:
Linux Mint Cinnamon 20.3 ( ubuntu 20.4 core )
Nvidia binary drivers ( 3060 )
PluseAudio
OBS 27.1.3 ( flathub )
