sound problem (fixed) - ASUS M3A78-EM

After installation of openSUSE 11.1, sound was not
tested. Today when run, it shows error like no
sound card working. While using yast, it failed to
configure it with error "module snd_hda_intel"
not found. Various forum, mailing list, there
was various method, but my problem was strange
with 'module not found'. I was not able to find
how to find module.
------
$lspci
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
------
Finally I find that alsa-driver package was not
installed on system from Alsa Project.

Download, Compile and install.
finally
$modprobe snd_hda_intel
works and with reboot sound works fine.
later found package "alsa-driver-kmp-pae" for same
work. This was small fix after I found pacakge:-)
