ac97 audio trouble

[MidnightToker]

I just installed slackware 12 today and i'm having some trouble getting my realtek ac'97 sound card to work. first i tried installing the realtek-linux-audiopack-5.01 driver from the realtek site using the automated install process but when the installer tries to detect a card or onboard chip, it comes up with nothing. I'm 100% sure it's an on-board realtek chipset 'cause that's what was installed on XP before i got rid of it :P I did kill ALSA related processes before installing btw so that's not causing a problem. Keep in mind i'm really new to linux so try and keep things simple for this noob :)

I have sound set to ALSA in KDE ControlCenter/Sound System and any time i try to restart the sound server, i get the message; device: default can't be opened for playback (no such device). Please help a noob out!

ok i got it working! sorry about the wasted post. looks like the driver came preinstalled in slack after all but it just wasn't configured. when i tried to installed the drivers from realtek, it must have broken something and prevented alsaconf from finding any audio hardware. after reinstalling slackware and then running alsaconf, the soundcard was detected, and now i'm set
