Audio output per sound group

[ffernn-dev]

Hey there, not sure if you're still around, but given you've poked around with mc's audio code before I thought I'd ask here.
I'm interested in being able to send Minecraft's music on a seperate audio channel so that I can listen ingame, but ignore it in OBS so that I can add different music later. I'm using pipewire on linux so I can do cool things like this :)
