I have solved it, but not that I think it is connected to kernel version. Some Intel cards require program hdajackretask, and it creates (somehow) /lib/firmware/hda-jack-retask.fw and such did not exist after upgrade. It can be that FHS upgrade removed that file, but it should not in my opinion remove anything from system that is not confirmed by the administrator.
But it can also be that Hyperbola removed some files from /etc/modprobe.d/ so I cannot know why I lost sound. But it is not due to kernel, rather due to hdajackretask and missing firmware after upgrade.
I fiddled with hdajackretask and I got it working, I do not know how, don't ask. I just installed it, it created firmware and /etc/modprobe.d/hda-jack-retask.conf and later by fiddling with pavucontrol-qt I could get it to work.
So thread is now closed.
Content of the file:
# This file was added by the program 'hda-jack-retask'.
# If you want to revert the changes made by this program, you can simply erase this file and reboot your computer.
