Also for the low latency kernel and other versions 5.4, 5.13, 5.14, 5.17. So it is not kernel specific. It must be a problem with configuration, but reinstalling doesnt fix it. EDIT2: it turns out this is caused by the cloud-initramfs-copymods package mounting over modules locations. Removed it and reinstalled kernel modules package (extras didnt seem necessary, but probably prudent too). This affects several different kernels I've tried in 22.04. This post basically sums it up: https://unix.stackexchange.com/questions/405146/removed-lib-modules-folder-after-every-reboot detailed answer: https://unix.stackexchange.com/a/499580/346155 And this one from upgrading from 20.04 to 22.04: https://askubuntu.com/questions/1400470/kernel-module-not-getting-installed-after-upgrade Basically, for some reason the kernel modules are being mounted over after reboot. My image was built on top of a cloud-init image, but removing the recommeded package "cloud-initramfs-copymods" that mounts over modules didnt work for me. Adding the snd_hda_intel module to the boot config /etc/initramfs-tools/modules did fix my issue for this module. But how many others will not be available? --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu80 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: user 2189 F.... pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: KDE DistroRelease: Ubuntu 22.04 IwConfig: lo no wireless extensions. enp1s0 no wireless extensions. virbr0 no wireless extensions.
