I recommend you follow this audio troubleshooting guide for openSUSE:
http://en.opensuse.org/AudioTroubleshooting
Some hints reference that guide, and reference the script output you provided. You have v.1.0.14 of alsa installed, and you have an alc268 hardware codec. With that codec you must have at least v.1.0.15 (or even better v.1.0.16rc2) of the various alsa applications installed to get audio. The audio trouble shooting guide will give you guidance for that.
The zypper example given in the guide assumes you have the latest openSUSE kernel. You do not have the latest kernel. If you insist on using the older kernel version, then instead of the zypper commands in the audio troubleshooting guide, use these commands in a konsole/xterm with root permissions:
Note, you will need to reboot after installing the latest alsa. Also, you will likely need to have to edit your /etc/modprobe.d/sound file, either editing, or adding, a line for your alc268. ... ie possibly something like this:
