WebCord is an “alternative client” for Discord, although it’s just running the Discord webpage in electron. Recently it updated its electron version so it supports sharing audio as well as video.
I tried it out today on mint (x11, pulseaudio) and it works flawlessly.
I can tonight but i always forget to check back into lemmy and jerboa sucks at notifying on post responses
EDIT: tried it on my kde plasma wayland setup on my tablet and tried streaming my firefox window, and no dice. I checked in qpwgraph and no new linkage was made in the audio channel and nobody could hear my desktop.
Does this rely on wireplumber or can i keep using pipewiremediasession? Wireplumber breaks too many things for me to use.
