I can't see there is any PCI device from the alsainfo.txt log, if the kernel can't see the device it could be related to something that is below the kernel level. You can also upload the output of 'lspci -vvnn' for us to check. Could you also check if there are settings in the BIOS about audio? Perhaps you can try to reset the BIOS to the default and see what happens.
