soundcard not detected
Since a few updates back of my o.s. (kde neon) my soundcard was no longer detected. After many steps and a bug created at https://bugs.kde.org/show_bug.cgi?id=429485 , the only thing that worked was doing:
- sudo rm /lib/udev/rules.d/90-pipewire-alsa.rules
- sudo reboot
From those steps and help from Harald Sitter it seems that the udev rules break discovery of your audio devices.
The bug at kde is now closed with status: Resolved upstream
