And now I rebooted again after yet another kernel update (I did not change anything apart from "sudo dnf update" and reboot). Now it is working again. I have attached the output of alsa-info.sh for the non-working case. Could it be that the kernel update had nothing to do with it working now and that it switches between working and not working "randomly" when rebooting?
