Manjaro Nibia 20.2.1 (64-bit, Xfce 4.16)
Lenovo ThinkCentre M58 6303W2N (Audio Intel Q45, 8 USB ports: 2 x front, 6 x rear)
Dericam W3 1080p Webcam
My webcam takes pictures and record videos but its microphone works randomly (1 - no sound at all, 2 - static beeping, 3 - perfect sound). It does not depend on me changing the settings, but it is quite random and depends on USB port. Unfortunately, the working USB ports (one in front and one in the back) do not work all the time.
