Yesterday I suddenly lost sound on my pC. I use a headset so as not to disturb my wife. I went to DELL support and downloaded the latest driver and installed it on my PC. Everything looks ok, but every time I try to configure it, I get a message that "no jack information is available". I have tried both front and rear jacks and still get no sound. Any clues on where I go from here?

Before our users can assist you, we need to know the system model, operating system, and specific audio device.
You have to reinstall DOT NET 2.0 and 3.5
then install Directx June 2010 patch.
You download the file and extract to a folder then run DXSETUP.EXE as administrator.
Then install the Vista Driver because these didnt come with windows 7 and therefore do not have WIN7 Drivers.

This means you have to install Legacy Direct show as well as DX9
and DX10 drivers from the june 2010 PATCH.
You download the file. extract to a folder and run the dxsetup.exe file as administrator.
You also have to re enable DOTNET and Legacy Direct play.
I finally did everything you told me and the error messages went away, the audio control when I hover over it says (speakers/headphones 95%) so it recognizes the jacks. BUT I still can't get any sound through my headphones. I am going out and buy a new pair to see if that is the problem.
