From the bug report you quote, it appears your sound works:
https://bugzilla.novell.com/show_bug.cgi?id=371050

Is that you on the thread? If not, I really can't tell what you tried.

Did you install alsa-firmware? Did you try yast? alsaconf? edit your /etc/modprobe.d/sound with various options? ....

How about trying to work your way through the audio troubleshooting guide:
http://en.opensuse.org/AudioTroubleshooting

... and if nothing else, post the output URL from the two diagnostic scripts:
http://en.opensuse.org/AudioTroubleshootin...led_information
... such that we can check if you made a mistake in your configuration/setup.

Also, it would help if you posted here the contents of your /etc/modprobe.d/sound file.
