Got a computer that was made by HP, a1020n was the model number. Being a brand named computer means that it comes preloaded with lots of things I won't find uses for. So I basically deleted the original partition to install XP Pro. However, upon succesfully getting to the Desktop to set up everything, I noticed that there is no Audio Device under Sound properties in control panel. I don't recall having disabled it in the first place, so I went back to the BIOs and looke, the On Board Audio setting was set to Auto, I've tried changing it to say Enable, nothing changed. All that showed up under Multimedia, Game Controller under Device Manager were the Legacy Audio / Video Codecs. This is the first time I've ran into the situation where enabling it in BIOs doesn't do anything under the OS. Please help. Thank you.

so from what i understand its enabled in the bios but doesnt show up in windows. first off is there any yellow bubble things with exclimation points in them? if so its possible one of them is the sound card. if that doesnt help try finding out the manfacturers of the motherboard, not hp, and check the manual. their might be some jumpers you need to set or something.

I think this is what you want: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?dlc=en&lc=en&os=228&product=459880&lang=en&cc=uk&softwareitem=pv-29675-1 there are other drivers on the HP website you should install such as the chipset drivers

You hosed your chipset drivers when you deleted the original partition and if you reinstall them (as pointed out above by Dr. K. Kennedy) many of your problems will resolve.

The legusy support is used for DOS based games. If you don't need this then disable that option as it uses an IRQ.

Thanks for the input, guys/gals. It was the problem with the PCI device and a driver was required. However, during my 1st format and install, XP assigned my local HD the letter I, the drivers (in exe format) offered by HP defaulted to extract to C, which was assigned to a removable drive that has no space on there to take the extraction. So, not being able to assign the letter to the system, I ended up deleting the partition and reinstalled, this time my local drive was assigned the letter C, and I was able to set up the audio with no further problems. Thanks again for all the help.
