I am fixing a friends computer, and one of the problems is that the sound does not work. I narrowed it down to the device drivers, so I reinstalled them. Unfourtunately, that did nothing, throwing a code 10 in the device manager, even though I went to Acer's site and downloaded the right drivers. I checked the BIOS next, but the BIOS didn't even give an option to do anything regarding sound. Anyone have any idea what is going on?
