I have an NVidia GeForce 9500GT that I have connected to my motherboard's SPDIF output header with a cable. I have it connected to my TV through the DVI port, and added the HDMI converter at the end. It is plugged into an HDMI port on my TV. The video works great, but there is no audio. I went into Playback Device properties, but the only option is for the internal Realtek sound card. This is a new install of Windows 7 x64, and I have installed the latest drivers from the Realtek website for the HD Audio. Why is the SPDIF output not showing up in Playback Devices? I looked in the BIOS, but the only mention of anything to do with audio is to enable/disable the onboard sound...nothing about SPDIF at all. Am I missing something? Any help would be greatly appreciated!

Here is a screenshot of my Playback Devices properties. It shows only the normal Realtek output. It also shows that I have it set to show disabled and disconnected devices.

Is there a BIOS setting for SPDIF? Also, make sure the connections are correct on the motherboard. See page 2 of this guide.

The only setting in BIOS is to enable or disable the onboard audio.  Nothing about SPDIF at all.  I should mention that the PC is an Acer Veriton X4618G.  It has an SPDIF header marked on the board, which is the "4" pin type.  I do have it hooked up correctly.

If the connection is correct I wouldn't know why SPDIF is not detected. Have you tried the Audio driver on Acer's website. I would think the latest Realtek driver would work though. There are no yellow exclamation marks in Device Manager are there?

 

Here is the service manual for your reference.

I originally tried the audio driver from Acer's website, but read somewhere to try the driver directly from Realtek...which is the one that is currently loaded.  I have seen that manual before...and I do have the correct header for the SPDIF.  I'm at a loss...

So am I. I looked at that card. Is there any way you could use the TV out port on the back of the card? Probably does not make a difference but I read where the HDMI adapter was only supposed to be used on DVI-I connector 2.

If you have the Realtek Driver installed, go to Control Panel and open the Realtek HD Manager. Is there anything related to SPDIF. It may be called Digital Output.

My 9500GT does not have a TV out.  It has 1 DVI, 1 S-Video, and 1 VGA.  You can see some specs here:

Here is a screenshot of the Realtek manager.  It's like the system doesn't even recognize that there's an SPDIF option available.

Ok, I tried using a DVI to HDMI adapter at the card, then running an HDMI cable to the TV.  It still doesn't give me an SPDIF option in Windows at all.  Here is a picture of the SPDIF header on my motherboard (I put SPDIF on pin 3 and Ground on pin 4):

Here is a picture of the front of my card.  It only has 1 DVI connection, along with SVideo:

Also, here are pictures of my BIOS main screen and also Integrated Peripherals (which is the only place where there is anything about audio whatsoever):

I do not understand why it is not working. From your picture of the 4pin SPDIF header pin 1 is +5V, 2 - empty, 3 - SPDIF out, 4 - Ground. You have connected the cable correctly. If SPDIF was detected it should show up in the Realtek HD Manager. I am at a loss on this.

 

Edit: If  you can afford it, you might want to get a card with a dedicated HDMI port.

 

If you motherboard has a PCI-e 2.0  X 16 slot

Maybe that's what I'll do.  Maybe it's the card...maybe the OEM BIOS doesn't support SPDIF.  Either way, I've put enough time into trying to figure this out.  I'm getting that GT 610 on Newegg for $40 with a $10 rebate...not too bad.
