Public bug reported:

The Problem:

I installed Ubuntu 10.04 (Lucid Lynx) using the amd64 Desktop
configuration.  My sound card was not detected by default.  No devices
were shown under System -> Preferences -> Sound -> Hardware.

dmesg showed the following error: hda-intel: no codecs initialized

Sound Card Specs:  RealTek 888 (ICH10).  Integrated into a Gyabyte GA-
EX58-UD3R motherboard.

My Fix:

(spend several hours researching problem)
Edit /etc/modprobe.d/alsa-base.conf
Add line: options snd-hda-intel model=6stack-dig
Reboot

Requested fix:

Please make necessary changes so that this hardware is auto-detected.
