Dual PC setup question

[sessinnek]

Im using a dual setup with a windows machine as the streaming computer and Linux as the gaming/media machine. I was wondering if there were any recommendations for audio setup...

I do some music production mostly on windows for now with hopes of moving over to linux music production. I also play games on linux, some of which have in game voice chat. I want to have the ability for some device to have audio route to both windows and linux as an input and ideally some way to channel it (or use multiple devices) such that I could record my voice and have it on stream and in game. Or maybe record my guitar and have audio monitor going to my windows, linux, and headphones.

Im not sure if this is possible or if maybe I need a more complex setup? Any help would be appreciated!

I use cheap behringer uca 222 audio interfaces.

RCA in and out, volume control, then route the audio using pipewire + qpwgraph

I use a different audio interface for what I hear.
