i recently got a used optiplex. the owner said it has the ac97 on board audio. i have run belarc, winaudit, device mgr and there is NO indication of what the onboard model is. i opened the cover but could find no meaningful #'s - so i came up with a scheme to bail me out!. i have an sb Live! ct4780 card from an old dimension 8300 i had. can i use this card in my optiplex and i was gonna use driver R69382. does this sound do-able...anxious to hear from you, aloha
