nVidia nForce Realtek audio SPDIF is not detected or working
I have recently bought a new Gigabyte nForce4 GA-K8NF-9 Motherboard that has a Realtek audio which is onboard. It used to work fine Windows XP Media Center Edition 2005 but the problem started when I upgraded to Windows Vista. The issue is with the SPDIF which is not functioning properly as before. There is only 2 channel audio that i am getting via the regular audio jack. There is nothing i can do to turn on SPDIF jack after looking in the settings on the Speaker control panel. I have downloaded the new drivers from the Realtek website but am unable to install it on Vista. Any ideas?
