Dont now how to do.. appreciate if you could tell me the steps.

This won't work.

A HDA sound system consists of two chips, the controller and the codec.
In this case, the controller is built in the southbridge, and is from Intel. The codec is a separate chip from VIA.

The correct sound driver to use is for the controller, so it's snd-hda-intel. (Actually, all other controllers are Intel compatible, so this driver would be used in any case.)
The controller driver automatically loads the correct module for the codec.

The problem is probably that the driver doesn't know how the codec is wired in that notebook.
Try a newer kernel (Fedore 11 might be too old), and/or setting the "model" option of the driver.

Oops!.. I really didn't know much about the sound driver functioning. Thanks for info.

However, I am wondering how to setup the model option for the driver. Appreciate if you get some steps to do the same.

I searched a bit on net..so do I have to add something in

/etc/modprobe.conf

example..options snd-hda-intel model=XXX

Appreciate if you tell me for which driver should I use the "model" option and which model should I specify.

The model options are documented here: HD-Audio-Models.txt.
However, it seems no model options are needed for any VIA codec. Try a newer driver/kernel.

try deleting /var/lib/alasa/asound.state and then reboot

You need to feed experts with information before they can help you. There are many experts here.

I have a similar problem with the same via controller on a PCChips P47G motherboard.
