[arch-general] Help - Sound Disappeared -- Really! All modules -> Gone?? (kernel bug?)

[Flavio Costa]

I'd guess that you have a corrupt filesystem and due to an fsck (or
something else) the modules are gone.

Try doing a "ls -la
/lib/modules/2.6.31-ARCH/kernel/sound/pci/hda/snd-hda-intel.ko".
And this: "pacman -Q kernel26 | grep snd-hda-intel"
