Audio-In/microphones not working with most applications (Plasma/KDE)

Since at least 3 days my Audio input is not working properly anymroe. I first noticed it with Zoom. When joining a call I could choose “Join with Audio” and even though the audio seemed to work It would spam the screen full of “Audio XYZ connected”. I.e. it would constantly connect and disconnect 10s of different things.

I also realised that my browser(s) (i.e. firefox and chromium) are unable to find any audio hardware. I.e. if I use websites that have some form of Audio input there simply is no dialogue opening that asks for permission to use audio. And it seems that the browers cant even find any microphones connected in the first place.

I think I know what you’re talking about. Any time I join a zoom or a discord call it flickers like crazy, right? Try bumping your volume once in software, either through a hotkey or like the volume adjust on a USB headset, etc. That seems to clear it up for me.
