No sound in KDE with Sony Vaio PCG-818

I'm having some issues getting sound to work with my Sony Vaio PCG-818 laptop. I've used this laptop with linux in the past, with no problems whatsoever, but that's been more than a few years ago.

Sound works just fine if I log out of KDE and go to the console and just 'cat' a wav file to /dev/dsp. But I get no sound whatsoever in KDE. I have enabled the audioserver and have the volume turned to the max. I don't get any errors whatsoever from the audioserver, it just doesn't work.

I can't figure out why it's not working....

I got it to work....
