Oof, I feel you on the video call thing. I use a semi-complicated setup of switching between (7.1 surround) speakers and headphones, plugged into two separate sound cards, too… And a Zoom recorder connected with USB for sound, and Droidcam for a webcam. So many possible points of failure. I had it all working during COVID, but when I have to video call now, I just install the needed app and use my phone 🙈
(Of course, being able to do this stuff in the first place is a testament to the freedom Linux provides.)
