I have a secondary discord account I use primarily for streaming, It works pretty well and I haven’t had any issues.
I used to use the secondary account in a web browser and manually patch in the audio to it’s mic input with pipewire and a patch bay.
The main reason I use discord-screenaudio is because I’m lazy and it’s slightly faster than manually doing it; Also it allows you to actually have the audio come out from the stream like on the standard windows client, as opposed to using the mic input for audio.
You can manually remove all of the previous drivers and their GL32 counterparts, your flatpaks will still run as long as you have the newest drivers.
I’m not sure why they don’t get caught by the --unused flag, but they are definitely not needed from the flatpaks I’ve tested with.
