Sound Card in CentOS 5.2

[mentor]

Hi

I am having Lenovo 3000 G410 2049-44Q laptop. I have installed CentOS5.2 in that.
But I am facing a problem in my sound card. I am unable to get any output from my sound port. The card has been detected properly.

Following is the result of lspci command for your reference:

I'm not sure what could be wrong there are lots of pages out there that state the audio works fine in centos. here is one example I found doing a search on:

centos "Intel Corporation 82801H"

There are other links that show it doesn't work. I found this in the Ubuntu forums with a suggested fix.

Someone mentions:

It seems on ThinkPads, you need to make sure the modem is activated in the BIOS in order to get the sound to work. Seems the sound is "inextricably linked to the modem," so if the modem isn't activated in the BIOS, you won't get any sound.
