Problem with Creative 5.1 Sound Card

[Josh]

Hi,
I am newbie to centos, I installed CentOS , It recognised my sound card, but I don't see snd module loaded neither I hear any sound from it.
Here is lspci output when I grep for creative sound card, so it detects the card.
Multimedia audio controller: Creative Labs [SB Live! Value] EMU10k1X

How do I make it working, I did some search and it talk about install alsa driver, I did that but no help.

Thanks
Josh
