Realtek audio problem

I'm total newbie to Linux world, and my first day with Linux was a week ago. I got a new hard drive, partitioned it, installed Windows 7 first and then installed Opensuse 13.1 with KDE. I could not make the sound work on Opensuse. I've been searching for a week online, and tried everything I could with no success. I learned couple commands though, and my sound card model, codec, etc ... ... I ran alsa-info.sh and got the below information.

It doesn't mean too much to me but somebody with some knowledge might be able to help please by taking a quick look at.
on Windows 7: The sound did not work first when I started using it out of box, but I then installed Realtek driver and everything worked fine.
on Opensuse: I tried updating ALSA to the latest version, alsamixer, Audio Setup, Select Master Channel, Assign permission to user, Test sound, .. .. ... .. but still no success. I thought of downloading Realtek driver as I did in Windows, but I got stuck at the last step when I followed the Realtek instruction at "make install" command

zino@linux-l7ok> sudo make install
root's password:
if [ -L /include/sound ]; then \
rm -f /include/sound; \
ln -sf /home/zino/Downloads/AA/alsa-driver-RTv5.18/alsa/include/sound /include/sound; \
else \
rm -rf /include/sound; \
install -d -m 755 -g root -o root /include/sound; \
for f in include/sound/*.h; do \
install -m 644 -g root -o root $f /include/sound; \
done \
fi
install: cannot stat ‘include/sound/*.h’: No such file or directory
make: *** [install-headers] Error 1


Thanks for help
