Ok, when i plug in my speakers (Logitech X140) or my headphones (wicked reverb from wicked audio) windows 7 (64bit) says that nothing is plugged in and no audio device is installed. The audio works in ubuntu (on a separate hard drive) when i look in device manager under sound video and game controllers it has NVIDIA High Definition Audio for times. It wasnt working on a fresh install. The reason i was using ubuntu is that this started happening a while ago and i got no help so i switched to linux but now i want to have windows so i can play games.
Motherboard: Asus P5G41C-M (i have tried installing the audio and chipset and nothing)
Graphics card: Nvidia GeForce GTX 550 Ti
Onboard sound card
If you need any other info just ask.
