Vista - Onboard Realtek HD (Not Plugged In)

Hello,

My on-board Soundcard stopped working a while ago, I did have a USB headset but that broke (wire clipped). Now the only audio I have is media shared to my Xbox 360 and would like to know if I can fix my on-board Soundcard.

I have seen this problem on many forums as I have searched, some have been resolved with drivers, enabling the device, enabling in BIOS. I have done all I have needed to completely un-install and disable the device and reinstall. The others have not been resolved with either a useless request for help or a useless reply. The posts I have found similar on these forums are:

No Audio Output Device is Installed - Basic tasks I have already done with re-installation of drivers.

Message says "Speakers are not plugged in" - Not resolved, don't need to say why...

back panel not working for latest realtek driver! - Does not look resolved, but this is the problem, the back and the front...

I did wire the front panel to see if it was just the back panel, I could then by disabling front audio jack detection make it output, but I think I only got a hissing sound.

If you need any more information just ask, however, I'm going to be away for a few hours after this post.

Thanks in advance!
