Sound not working - HP DC7800

[Niceguy]

Hi friends,

We have a PC HP Compaq dc7800 Convertible Minitower PC,  I installed Win Xp prof ver 2002 with SP3 Genuine version . After the installation , all the drivers were automatically detected except sound . I downloaded from the HP website for my model and installed . Still no hope . I patched my PC with the latest updates from microsoft and still the same result .

Thanks in advance

Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio  must be installed first then install the driver.
