I seem to be able to detect the headset mic into "pavucontrol". I see sound captured, but the device is shown as "Headset Stereo Microphone (unplugged)". This device do not appear in the sounds parameter, but only in pavucontrol. That's a first step but I don't know how to fix from there.
So, take a look at them. Step 1: Launch the Zoom app and click on the settings icon. Step 2: Go to the Audio tab. Click on Advanced at the bottom right. Step 3: Click on the drop-down boxes . 484 758 31 768 635 92 183 457
