How do I configure a PCI Sound Card

Which exact sound card are you refering to?
Normally what you have to do is load the proper module (assuming your kernel supports that module) for the soundcard to work.
As in modprobe sound_card_exact_model_module

Which model is it ?
Please post the output of lspci

05:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)

The problem is that it is detecting three sound devices, and I'm getting static from my Rocketfish 5.1 pci soundcard, which is the repackaged Soundblaster Audigy soundcard that Rocketfish purchased apparently. I'm getting static with a bare hint of the audio that's supposed to be playing with the static in varying durations depending on the sound file length being played.

I'd appreciate help in making it work again, it used to work fine with the Ubuntu 10.4 original release, and seems to have picked up the static problem with the latest updates.
