Recently my laptop decided to crash itself, and unfortunately this meant wiping the harddrive and reinstalling windows. I then downloaded all of the (i assumed) correct drivers from dell. However the sound doesn't work. I think that this is due to the wrong audio driver, so how do you tell which is the correct one? There were three to choose from on the dell website, the first I tried said that there was no hardware to be configured, the second seemed to be accepted and so didn't try the third.
