I have an xp windows in a dual core intel system and the sound isnt working...the device is plugged in and not muted

Exactly which motherboard do you have?
Manufacturer?
Model-number?
Operating System? ( XP? 64-bit Vista? 7?)

sound card may have failed or the default sound drivers were changed or muted. have to look at control panel hardware sound card link. check that system sounds is in the default box configuration.

It doesn't look like you can get Compaq supported drivers for your laptop but you may be able to write down the brand and model of each device from Compaq's support site: , then go to the individual manufacturer's web site and get an XP driver for that device. e.g. Nvidia most likely has a driver for the GeForce Go 7200 video card posted on their site. Just don't count on calling compaq tech support if you have any problems. If this laptop has a TV tuner in it, that will most likely be a sticking point.

The Broadcom network controller, Intel WLAN card, and the Intel Chipset drivers can most likely be found on the individual manufaturer's web sites.
