nVidia nForce Realtek audio SPDIF is not detected or working

I have a nForce4 GA-K8NF-9 motherboard with a built in Realtek audio.

The trouble is it worked fine with MCE 2005, but when I moved to Vista the
SPDIF is no longer functional. I have audio, but only 2 channel through the
regular audio jack. I have looked all the settings in the Gigabyte UI that
Vista installed, and the Speaker control panel, but nothing allows me to turn
on the SPDIF jack.

I went to the Realtek site to get new drivers, but Vista didn't want to
install them because it said I already had current audio drivers.

Any help?

Do you have the latest nForce drivers from the www.nvidia.com website?

I just got it to work by installing the latest RealTek drivers.

Now I'm trying to figure out why my external USB HD is no longer being
detected after getting the S/PDIF working.

Arg!

Thank you.

I think many of my problems were trying to run Vista64, so I moved back to
Vista32. The most recet RelTek driver got my SPDIF working, and I see I can
have regular audio out or SDIF out; however, you can't have both active. When
I was running XP Media Center I was able to have both active so I can rout my
audio out on the back panel to different devices in my rack. Now I have to
make as choice which device I want to use.

Is this a bug or a feature that you can only choose one type of output?

I know Vista64 is 'special' with drivers, because of that I just tried
Vista32 on this box...
I know Vista very well since first betas, but may be there is a 32bit
driver that I didn't try yet... *Could you post here a link to that
driver please??* ... or else send a a mail to that...

Do you know if powerdvd detects your S/Pdif on vista32?

This actually may not be a problem with Vista and the audio drivers. I
was having similar problems and through my reading I discovered that
Power DVD version 7.3 doesn't support multi-channel audio output via
HDMI. I know you are trying to use the SPDIF output and to be honest I
cant remember if the version 7.3 issue was multi-channel audio all
together or if it was just an HDMI issue. It is something you might
look into. I had to either upgrade to version 9 (version 9 ultra for
HDMI in fact) or look at using another player. I went with another
player (Arcsoft TotalMedia theater) and I have not had a problem since.
