This is what I had done... I added the line hda intel to
gedit/etc/modules per the instructions listed below when I noticed the
sound card wasn't working.
Manually starting the audio driver
Open a terminal and type
sudo modprobe snd-[NAME OF YOUR SOUNDCARD'S DRIVER]
For example, my driver is named "via82xx" so I would type
sudo modprobe snd-via82xx
After this, try playing sound. If you hear sound, it means that your
installation isn't auto-detecting your sound card, but you have all of
the right software. This command temporarily loads the sound driver, but
it will not be there on the next reboot.
You can override the auto-detection and force your computer to load the
driver on every reboot by adding the driver (i.e. snd-via82xx) to the
/etc/modules file. Type
gksudo gedit /etc/modules
and add your sound driver as the last line of the file. Save the file,
and reboot to verify that the sound is working after a reboot. Even if
this step works, you should file a bug with the Ubuntu developers at
launchpad.net if you haven't already so they can try to understand why
your computer isn't auto-detecting the sound card.
Refreshing/reinstalling the drivers
Sometimes, sound might be configured correctly, but for some reason or
another it stops working. If this is the case, you can purge your custom
changes, and reset your system to a clean base. This may clear up your
problem and restore your computer to a working state.
Open a terminal and type
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils
linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
This will purge any custom configurations that you've made, and any
hand-compiled modules that you've built, and restore your sound stack to
the "Official" Ubuntu core.
