Okay, I'm in a jam. I upgraded from 98 SE to 2000 Pro and lost my sound. I did this once before, was able to find the driver I needed from driverguide.com but for the life of me, I can't remember how I found it. The only info I have is that this is an HP Pavilion 8665C that came with Win98 SE and when I'm in Control Panel and click on Sounds and Multimedia, click on Audio, it tells me there is no Sound Playback Device, no Sound Recording Device, and no MIDI Playback device, yet I can't click on anything else to get any more info. All I remember is that Riptide was a part of the driver name I used, Legacy Audio is a name I get from My System info, but I'm told that that is a generic name Microsoft uses. Please, although this computer is only a temporary situation, it's what I have for about 2 months.
