After a very brief (~20 seconds) review of your information, I can tell you that you are supported, but you will need to upgrade your alsa installation. You are currently running 1.0.12rc1 (very old in alsa terms). Your system is supported in 1.0.14.
There are two ways that I know of that you can use to upgrade your alsa drivers (without installing a different distribution). The first is to download the latest drivers from http://alsa-project.org
, the second is to download my build environment
and use it to create rpm packages for openSuse (the distribution you are currently running). To use my build environment, you will need to install the kernel-source or kernel-devel packages, rpmbuild, and other basic kernel build tools. Yast should be able to figure out what all you need. Once you have the tools in place, just untar my build environment, and run make as root from inside it's top directory (./my-build). Then run audio-install to install the packages.
