I have a Dell Dimension 8400. From out of the blue, my sound stopped working. Shortly after this, I started getting an error message when I booted up the computer. The message is a "Found New Hardware" wizard for a Multimedia Audio Controller. Despite my best efforts, I can't seem to get the wizard to find the correct audio driver -- the wizard always ends with the message that the hardware could not be installed because the wizard could not find the necessary software. I have tried directing the wizard to the driver CD that came with my Dell but that didn't work. On my own, I installed the audio drivers that came on my Dell CD and that also does not work. I also downloaded the most up-to-date drivers from the Dell website, but did not work. When I open Device Manager, under Other Devices, there is a yellow question mark next to Multimedia Audio Controller (two entries), PCI Input Device, and PCI Modem.
My audio device is ADI 198x Integrated Audio.
It seems as if my computer is detecting the audio device but not letting me install the drivers.
