I would try resetting your sound card settings, I've had problems where my laptop "forgot" my sound card and this resolved it

sudo aptitude -y purge alsa-base && sudo aptitude -y install ubuntu-desktop

I installed a sound card but when I go to System->Preferences->Sound and go to Hardware it's not showing anything at all. If I boot from the Live CD then it will show the card and it works. How can I make my Linux installation detect this card?

I was thinking that I could somehow copy the necessary files from the Live CD to make this work, but maybe there's an easier way.

  If sound works with the live CD, it should work with an installed system too. Are you running the same kernel on both (if in doubt, post the output of uname -a on both)? On the live CD, what driver is used (ls -l /sys/class/sound/audio/../../../driver/module)? Are there any messages related to this driver in /var/log/kern.log?

  The kernel has been updated from the Live CD. There's a lot of messages in /var/log/kern.log. What should I be looking for?

  in /var/log/kernl.log, you should be looking at least for the module name, and for keywords like sound and audio and snd and alsa; there may be stuff not covered by these keywords, and there I'm afraid I can't say any better than anything that catches your eye.

  Please post the link that you get when you download alsa-project.org/alsa-info.sh and run it with bash (NOT sh)

Didn't work. I think the problem is not with Alsa since the system doesn't even see the sound card. I think Alsa is just a way to communicate with the sound card, but detecting sound card hardware is probably some other program's job.

I'm not using ubuntu but it is alsa (kernel module) job to detect sound card. Possibly it is job of another program to install sound driver.
