On wayland (KDE Plasma) it’s not as seamless. For me it creates two sinks, one of which is voice channel and other is the stream audio stream. It wires my mic to both automatically and i have to manually wire the app audio to stream audio sink. So it does work with extra steps. I use qpwgraph for wiring.
For me it makes the sink for stream audio but wires my mic to it instead of the app or desktop audio, gotta rewire manually. After that it works
