Fedora 33 KDE spin. I recently bought a USB web cam with built in mic. Works fine on Windows 10 on same machine (dual-boot). When I select the mic using alsamixer, I am able to move the volume up to mid-level. But when I use Zoom for a meeting, and start talking, within a few seconds the mic level drops to 0 and meeting participants can't hear me. I tried using Audacity, and it seems to keep the audio level fine for doing a sound recording. Where to look, what to try?
