It's an HP Pavilion with P4, and its original OS was WinXP Home Edition, but since I bought it used on eBay, I didn't get the installation disk with it. Consequently, I had to install Win2000 Pro off the disk for my other computer. The computer now recognizes some of its drivers, but not all. It was a heck of a time to get the video drivers installed, but I still can't get any sound at all out of the speakers.
I did the obvious stuff, like opening the Sounds and Multimedia Properties in Control Panel, but none of the default sounds are accessible, and the volume slider won't move. In Device Manager, it says that all of the Sound Controllers (audio codecs, etc.) are "working properly", but under the Multimedia Audio Controller tab it says there are no drivers installed for it. And yes--I've tested the speakers (they're fine) and they're definitely plugged in correctly.
According to Everest (that free utility that scans your system and tells you what hardware you've got), my PCI/PnP audio adapter is an Intel 82801EB ICH5 AC'97 Audio Controller. Under the category of Windows Audio, there's nothing listed. I tried downloading and installing the adapters from Intel, but can't figure out their installation procedure (something about adding a "-d" to the end of each file!?).
Am I missing something obvious here? Should it be this difficult to get sound to work with such a recent machine? Any advice would be greatly appreciated.
