Anybody seeing this problem on a Foxconn K8M890-8237A system, please
test this patch.  With it, sound should work without having to boot with
"pci=use_crs".  If you test it, please attach the complete dmesg log
here.  Thanks!

** This bug is no longer a duplicate of bug 662299
   Soundcard not detected (workaround: add "pci=use_crs" to GRUB)

** Attachment added: "quirk to turn on pci=use_crs on Foxconn K8M890-8237A"

Title:
  PCI/internal sound card seems to be detected, but is not available

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  In my PC is a VT8237A/VT8251 HDA Controller from VIA Technologies, Inc.
  When I open the sound preferences, I only see a dummy output.
  I tried a lot of commands to figure out the pronblem. It seems that the PCI sound controller is found.
  Somehow it is not recognized as an audio device.
