Hi, I'm having problems with the sound on my computer. I have a Windows XP Home Edition, with a Creative Soundblast PCI card. Last month, the sound suddenly disappeared. It showed the soundcard as installed and functioning, but Winamp would give an error message saying , "Bad Direct Driver Error Code 80004005". A technician looked at the problem and installed Realtek AC'97 Audio drivers. The sound came back and it worked without any problem. But after about three weeks, the sound completely disappeared again, and this time, its not even showing the soundcard as installed. At startup, the computer detects "Multimedia Audio Controller", but it isn't able to install it, saying that there aren't any drivers. And Winamp gives an error message saying "Device not found. Please select another device in configuration. Error code: 88780078." Also, right now, when I click on the Volume Control option through the start menu, I get this message: "There are no active mixer devices available. To install Mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware." I tried uninstalling and reinstalling the Realtek drivers again, but it doesn't fix anything. Can anyone please help me? I'm not sure which drivers I need to install or where to get them from. Thanks.
