so here is my total delema
I've downloaded the Sound Blaster live 5.1 drivers from Windows Updates... but i am not getting any feedback for audio... any suggestions anyone? yes all basic and sum advanced trouble shooting has been done... <--(8/23/2007)

(8/01/2007)--> I got the WDDM Drivers working for the SBL but then it craped out.... now it won`t detect in any of my PCI Slots i haven`t tested to see is the slots are toast but the cards not because it works in my other computer... so i re-enabled my Onboard no WDDM drivers from M$ for it... so realtek.com.tw it is... i download the AC`97 vista x64 drivers installs fine speaker (beside clock) has volume now not a red circle with a white x.... no audio....ok failed attempt so i remove tho`s drivers completely even with registry... install the HD realtek drivers installs fine well minus the fact they (were not designed for my chipset) speaker has volume and the "device is working correctly" well? I really do not know what to do... and yes i have driver signing completely disabled
