You are saying that even if you downgrade all the packages you upgraded it is still broken (?), this is decidedly odd. The strange thing is that initscripts/mkinitcpio/udev could not really do anything wrong as long as the correct module gets loaded. If I understood you correctly, that does in fact happen. Let's have a look at the module. Could you: "modprobe -rv snd_hdpsm && modprobe -v snd_hdpsm", and then post the output to the console and any dmesg output (and verify that your devices are not in /dev/snd)? Cheers, Tom
