Sound problems with ADI 1881 in Compaq 5WV280

[drivers]

So, I'm doing a fresh install for a friend who has none of the documentation for his box...however I do know that he's never installed any hardware in it. I do a reformat, and fresh install of 98se and am now in the process of installing the drivers for a few devices. All seems to be smooth with the exception of the sound card. I have done next to everything I can think of to get sound working. I have tried driver after driver from the compaq site, and abroad...windows updates...checking the bios...The device shows as working properly in the device manager, but when you check multimedia properties, there are no options to select the preferred playback device etc. Also when I attempt to check the soundmax mixer... I get an error mentioning unable to init directsound. I've been tinkering with this for hours , anyone have any insight?

forgot to mention this is onboard audio
