I'm having problems with my Audio in Windows 7 right now. It says my peripherals are not plugged in. "Speakers High Definition Audio Device Not plugged in". This happened today, when I was using the computer.
I've had Windows audio problems before, and they are hard to resolve. I've tried everything from reinstalling the default Windows 7 audio drivers to using some crappy Realtek drivers.
How is my speakers not plugged in?! Damn you, Microsoft.
