You could try to do simple arecord test in terminal: arecord -fdat -vv -Dplugw:0,6 -c4 /dev/null You should see vumeter activity from the built-in microphone. If that works, this starts to go a bit outside the scope of this list, but it sounds something in Alpine's user-space integration is missing. In e.g. Fedora and Ubuntu, ALSA UCM file is provided for these platforms and the shipped versions of Pipewire/Pulseaudio can expose the devices correctly to apps. You can do a sanity test (of your hardware) by booting a recent live image of either distro. Br, Kai
