ok, the sounds works with alsa support, but I want 5.1 channel sound system, and this onboard sound card is able to this, in Windows XP works good!
The source on the website just looks to be ALSA so I doubt it would be any different to what you already have. Perhaps someone with the same hardware could confirm that?
I have downloaded the source http://www.linuxant.com/driverloader/wlan/full/archive/fc3/kernel-2.6.9-1.681_FC3.stk16.src.rpm.zip but when I run: rpm -ivh kernel-2.6.9-1.681_FC3.stk16.src.rpm it not install!!!! just verify the package, but I can't find it in my system
It's not in /usr/src/linux.
Go to /usr/src/redhat/SPECS and you should find a kernel.spec file (or something similarly named). If you do "rpmbuild -bp kernel.spec", the kernel source will be unpacked and patched in directory /usr/src/redhat/BUILD.
Alternatively, as a non-root user you can do this following the instructions in the reference I gave you earlier:
