I've been using this program for a while (and it's GTK alternative Helvum), and it's quickly become one of my favorite tools. I picked up an inexpensive USB capture card, and the ability to simple pipe the audio stream into any sink I wish, such as headphones, speakers, OBS, etc. Is such a simple solution compared to struggling with audio settings trying to get the right combination. It's also probably the simplest solution to getting audio sharing in Discord, since they continue to not support it in Linux, even if the solution is still a bit of a hack.
