laptop microphone not working properly

Good evening, my build in mic stopped working. It produces only random noise, while i was on a Zoom call. I checked with gnome-recorder and confirm it's not the Zoom app. My wife's bluetooth headset works fine. My setup: UXEDO Pulse 14 Gen1 AMD Ryzen™ 7 4800H Arch Linux (obvioulsy) with current kernel and packages pipewire Tested on Hyperland and Gnome (both wayland and X). I checked settings in pavucontrol but looks all fine. Is there something else for me to check if it's a config/driver error and rule out hardware issue. Thanks Frank
