This driver is for a Conexant Riptide PCI audio device. I had updated an HP Pavillion 8665C computer from Windows 98 to Windows 2000 and lost the use of the sound card. I just updated the driver for the multimedia controller under Device Manager and it is working now. It is the only one I could find. I did find it on hp.com but it is well hidden. I can't remember where on their site I found it. Hope it works for you.
