I just reformatted a Gateway 3200S for my neighbor. Everything except sound; more specifically "Multimedia Audio Controller" succeeded. Gateway offers 4 different audio drivers-none of which solved the little yellow exclamation mark. I checked the Bios, it is updated. I have no idea why this Gateway will not allow Windows to install the audio device. This is not a Windows problem. Any ideas on how to get an audio device to install on this outdated machine?
