Hence, the problem lies either with getting the drivers to start working again or with Windows.
This is the first time this has happened to me in decades of using windows.
Dell Recommended: Microsoft has created a detailed step-by-step troubleshooter for common audio problems.
The troubleshooter detects the version of Windows your computer is running and adapts troubleshooting to match.
I have noticed that it is usually after windows or my firewall updates. So I am not sure if one or both of these occuring simultaneously is causing the problem.
To resolve: Right click on my computer and select manage. From surfing the web, it seems like a rather common problem. I'm going through the same thing but as of the time I came across this thread I think I'm a bit further along than you guys seem to be. If that doesn't match, u'll have to re-install ur sound card.
