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.

So the issue is:

See if adding pci=use_crs to your boot line fixes it. Reference: https://bugzilla.kernel.org/show_bug.cgi?id=16921#c5

IT WORKS!!! Thanks a lot for the quick reaction.

I like to make one comment on the sentence "to your boot line".
The change is rather simple, but it took me a lot off time to get to the right place.
I did know something about the grub.conf, but could not find it in the first place. After some searching I rebooted my PC with the live-CD of Ubuntu 11.10, but Ubuntu did not show up (I installed my PC with this CD-rom). Then I decided to start with an old Fedora 14 live-CD. I could reach my harddisk and mount it. I could get to the grub.conf file, but it was read-only. This was easy to change with chmod. Finally I added the extra parameter and rebooted.

My conclussion: I find it strange that a solution is rather simple. We could wonder why it takes such an effort to perform it.
Thanks to your knowledge my problem is solved.
Kind regards, Erik

You're welcome.
Just a note: with GRUB2, you should modify /etc/default/grub file and not touch the /boot/grub/grub.cfg file directly

I did not know about /etc/default/grub . The idea is great so I executed: "info -f grub -n 'Simple configuration'" as was mentioned in the file. Alas I must say, that it probably would have cost me more time to make the change in the boot line and verify the result. I think I had to use "GRUP_CMDLINE_LINUX=pci=use_crs" and then run "update-grup".

Thank you Dave, your fix works.
I was struggling with the same problem.

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!

The attachment "quirk to turn on pci=use_crs on Foxconn K8M890-8237A" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
