When using modules you can blacklist other sound cards (the M= B audio stuff for instance) and you get a little more visibility into what'= s is at least loaded. That way we could, at least as a test, run your setup= as a USB only system. If at that point you can record mix audio in somethi= ng like Audacity and play Audacity and Youtube through the Behringer then, = I would think, we would have determined that this is an application issue. > Will try that, why not? (Tomorrow morning) > While it shouldn't matter I assume you tried slack and discord with direc= t monitoring turned off and on? I would expect that off is the right way fo= r an application like these but it makes sense to at least press the button= to see if it changes anything. I tried discord; I heard the sound, the other side didn't. > > I'm really intrigued to see if we can figure this out. > I'm now compiling zoom, after removing the ~amd64 from the ebuild (I will not have an unstable qt all over my system).
