That should be lspci -v, but lspci -vn gives a bit more info

Ahaa! 2 soundcards, and I believe that Pulseaudio if installed has problems 
with multiple soundcards. I use Kubuntu (no pulseaudio), not Ubuntu, and I 
think that Pulseaudio is installed as default on Ubuntu 8.04. First thing I'd 
suggest is to disable Pulseaudio. This is easy, just sudo synaptic, and look 
for the package alsa-plugins-pulseaudio, and remove it.

The post from Frans makes a good suggestion, in checking that the speakers are 
connected to the default soundcard, as you have 2 installed.

Assuming that you have now disabled pulseaudio by removing the 
alsa-plugins-pulseaudio package, you should now be able to use alsamixer to 
access both soundcards.

Just typing alsamixer should display the settings for card0, which is the C 
Media one.

Type alsamixer -c 1 to get the alsamixer settings for the Audigy card

It is normal for audio apps to use card0, which in your case is the C Media 
one, so make sure that the speakers are connected to this one when checking 
out the sounds.

See how this goes for the moment.
