I know that there are lots of posts on this, but none have helped. The computer says that everything is working fine, but there is no sound from either the headphone jack or the speakers. Recently reinstalled windows xp. Dell Dimension 4600 From the dell site I have reinstalled the drivers for chipset, bios, and audio. Nothing has worked. There are no conflicts that can be seen. Nothing is on mute. there are 2 audio drivers that I installed: SoundMax Integrated Audio Creative Labs I think that Soundmax is the main one, but neither of them is producing sound. I have followed all directions from the website computerhope issues ch000208.htm with no luck.
