at konsole type lspci to see what it tells you about your sound card, then type lsmod and see if it is loading etc.
I'm newbie too, but I'm just learning some of these things, I'm in the process of getting my sound card and other sound cards working , I notice in the KDE control center you can look at the kernel and it tells you what is configured, disabled, enabled etc.
If I understand all this correctly the module must be put into, or added to the kernel, I'm learning this now. with slackware.
Not sure why, but learning how now. Hope this helps in figuring out how to get yours working.
I know that many distro's appear to load them for some cards and not for others automatically, this has something to do with the kernels modules, and I did confirm at least on my Slackware box, that my module is there, but not enabled, I'm learning how to compile the kernel for my system now in order to get the correct sound module to load up in the kernel.
Also there are devices you can add and start without compiling and rebooting also, but I'm too new to advise anything about this, I'm actually looking for advise here to add/enable the module for my sound card as well.
That all know wish I could help more
