[CentOS] CentOS 6 pci audio card not enabled

CentOS 6 up-to-date 2.6.32-573.8.1.el6.x86_64
Gigabyte GA-Z68P-DS3
on-board audio BIOS disabled.
Intel I5
Pny 550Ti video
Envy 24HT pci audio module

I want to use the fiber in/out of the audio card, but it is not listed 
in System/Preferences/Sound/Hardware, only the HDMI is available.

It was installed in the pci slot when the system CentOS 6.0 was installed.

I have searched all over Google, but can't find a solution.

Does anyone have a solution for this problem ?

Advice will be appreciated. thanks in advance!
