Hi, im working on my friend's computer here. i gave it a fresh install of xp sp2 about 3 weeks ago, and the sound was working just dandy, then all of a sudden, the sound stopped working and was replaced by motherboard beeps =P obviously the first thing to check was the drivers. windows said they were working properly, so i uninstalled the device, and let windows reinstall the drivers. same deal, said they installed fine. looking into the sound properties in control panel, it says "No playback devices" "no recording devices" and "no midi playback devices" all in grey. i figured his onboard audio card had just died, so i brought over my spare sound card, a soundblaster audigy 2, in great condition, which i know works. installed the drivers from creative's website, same exact thing. device manager says "installed and working properly" and sound properties says no devices installed. i then scheduled a disk scan and restarted the computer, it didnt find any errors. does anyone know whats going on? sounds like a registry problem of sorts. or some obscure windows problem. really dont want to re-reinstall windows, if possible. thanks in advance!
