Answer:
With Gnome2.28 i got really issue to make it working . the alsa drivers and the mixers dont help . finaly decided to search from google and to check experience of people with this driver issue .
This is the output of my lspci:
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
the only working methode is to install driver from the OSS (opensound system)
Go to http://www.4front-tech.com/download.cgi
download the package for your Linux or Unix version
reboot the machine .
test the sound with :
[pirat9@Unixmen-Host99 ~]$ osstest
Sound subsystem and version: OSS 4.2 (b 2001/200910230524) (0x00040100)
Platform: Linux/i686 2.6.31.5-96.fc12.i686 #1 SMP Fri Oct 23 19:53:24 EDT 2009

its realy a good job from the oss team ,im now enjoying with my music .
please ask is you have any question



Why always I am looking for help, the answers always have to be done on the command line ? - like other novice linux users I don't know how to use the command line -
Why people who post help, stop assuming all linux users Know how to use the command line? why not to do a graphic method for people migrating from Windows?
