audio issues

this is kind of a n00b problem but i simply cant find a way around it.
i have a presario V3000 ( service no V3122TU) with a celeron processor. i recently reinstalled windows ( XP service pack 3) and all was well except that i had no sound. the drivers available with hp & compaq didnt work at all. i was adviced to change the XP settings to believe that it was a service pack 2 and not a service pack 3 , load the drivers & revert to service pack 3.
the trick worked but the audio volumes, despite all levels being turned to maximum , remain barely audible. do i need new drivers or is there some other solution?
i know this may not be a particularly challenging problem for the experts here but would be grateful to anyone who can shed some light on it.

Did you try the Microsoft UAA HD Audio driver when you performed the SP2/SP3 switch? If not, it may be worth a shot.

 

Also, you might try reinstalling your chipset drivers before the UAA and audio drivers.
