I own a Compaq Presario SR2038X computer. I have upgraded the memory (4Gb), Processor (AMD X2 6000+), Hard Drive (1Tb) and OS (Windows 7, 64bit).
I recently upgraded the video card to a GeForce GTS 250. I use the DVI for my main monitor but use the HDMI for my flatscreen HDTV. I get no audio out of the HDMI, after reading from both the video card manufacture website and NVIDIA's web site I am supposed to use the S/PDIF to pass-through the video card. I have a cable for that but the drivers do no recognize the onboard S/PDIF (Internal not external).
Does anyone know how to activate the on-board S/PDIF?

This is your motherboard. Did you plug the SPDIF from the GTS 250 into the motherboard (upper left hand corner)? Be careful with the plug polarity.
What driver level is your NVIDIA card? What level is your Realtek driver?

You might have to set the HDMI as the default device in the Sound control panel and in the Realtek HD Audio Manager. The down side is that your PC's speakers will probably go dead.
I am running Realtek 6.01.6083 and there is a later version at the Realtek site.
There is a SPDIF digital output port on the back of the PC. I wouldn't think a cable would be necessary to get sound to your TV since HDMI should carry the sound. However, it might save some steps when switching between devices. It's just a thought.
