I Have the solution for the sound driver of HP Compaq
Presario C700 on windows XP.
First Please Download the driver (Conexant HDAudio 221_XP)
from the link.
Now you have to do the following steps:
1- Go to device Manager and open (Sound, video and game
2- Check if the (Conexant HD-Audio Smart Audio) is
3- If not recognized go to the next point, if it was then
right click and go to properties then under the driver tab click uninstall
driver and now scan for the uninstalled hardware and follow the next
4- Under Device Manager again open (Conexant HD-Audio Smart
Audio), now right click and chose update driver.
5- Now Click on (No, not this time) and click Next.
6- Now choose (Install from a list or specific location
[Advance]) and click Next.
7- Now choose (Don't search I will choose the driver to
install) and click Next.
8- Now Remove the tick (Show Compatable Hardware) and click
9- Now you should Browse the file you downloaded (Conexant
HDAudio 221_XP) and open XP32 and locate the (WiSVHe5.inf) file.

problems should be solved.
