It resolved itself. Sorry to bother you. I listed all installed Linux kernel packages (dpkg -l | grep "linux\-[a-z]*\-") and kept only the 6.2.0-26 versions. Then I removed unused packages (sudo apt autoremove) and afterwards reinstalled 6.2.0-32 (sudo apt install linux-image-6.2.0-32-generic linux- modules-6.2.0-32-generic linux-modules-extra-6.2.0-32-generic linux- modules-nvidia-525-6.2.0-32-generic linux-objects- nvidia-525-6.2.0-32-generic linux-signatures-nvidia-6.2.0-32-generic). Now sounds works again! (I don't know if WiFi was affected, but it works now.)
For reference, I attach the dmesg logs without timestamps (sed 's/^\[ *[0-9]*\.[0-9]*\] //') from the original problematic 6.2.0-32 kernel and again after reinstall. The first substantial difference I could spot is after "PM: Magic number" it no longer says "acpi AMDI0020:02: hash matches". ** Attachment added: "dmesg log of 6.2.0-32-generic before and after reinstall" https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.2/+bug/2036342/+attachment/5704061/+files/dmesg.zip -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.2 in Ubuntu. https://bugs.launchpad.net/bugs/2036342 Title: no sound cards found afer kernel update from 6.2.0-26 to 6.2.0-32 Status in linux-hwe-6.2 package in Ubuntu: New Bug description: After the update from kernel 6.2.0-26 to 6.2.0-32 under Ubuntu 22.04 LTS, there are no more sound cards found. I can reliably reproduce this by switching in the grub boot menu between the kernel versions. I used sound over HDMI of the NVIDIA Corporation GP108 [GeForce GT 1030] and it used to use the module snd_hda_intel. Now, a symptom is that `aplay -l` reports "no soundcards found", and neither does any other program. I had similar problems after the Ubuntu update from 5.19.0-43 to 5.19.0-45. I reported this to the offical linux kernel mailinglist yesterday ( https://bugzilla.kernel.org/show_bug.cgi?id=217917 ). They have sent me here. Indeed, I now tried the vanilla "mainline" kernels 6.2.0-rc8 and 6.5.3 - and there the sound cards are correctly found. I am attaching logfiles and info from /proc for the different tried kernel version that are hopefully useful. Please let me know if there is more info I can provide or things I could try to narrow down the problem.
