CPU to TV/Surround Sound Receiver Issue

After spending an hour or so trying to read through the 1,000's of HDMI sound issues, I decided to just register and post my problem because every "solution" I found is something i've already tried.

I have a HDMI cable going from my Desktop tower to my receiver, with HDMI output already as my default for sound. I get nothing, no music, no test sounds, nada. I tried to update my sound/video drivers and all of them said they were up to date. The receiver is on the correct input setting.

I also tried to back-feed it through my TV, with the HDMI going to the TV first, with my Digital Optical Audio cable running from my TV to my receiver. Again, no luck still dead as a doornail.

My Media Player is already set to playback through HDMI, and I cannot get sound from anything on my computer period.

Does anyone have a clue what to do? I'm out of ideas and honestly out of patience. Any help would be appreciated.

I have a Nvidia GeForce GT 220, and it has an HDMI output. I only see VGA/DVI/1 HDMI on the outside of the card. The Desktop is something I bought off Newegg awhile ago, it's not really any brand.

Asus Board, Phenom II, GT 220, 4 GB RAM, etc.

The option to select HDMI appears when I plug the cable in, but it doesn't appear to do anything. I've gotten it to do video to the TV, sound is my issue.

NVIDIA GeForce GT 220 PCI Express 2.0 x16 is exactly what NewEgg says, trying to find the other parts out. Used the purchase history to fill in more of the computer specs Fire said would be nice to have on my profile. Doubt that'll help much, and i've tried simply google'ing my video card to see if it does have this S/PDIF connection, and the only thing i've found thus far is people getting sound from 2 speakers instead of 5. That's not my problem, my problem is I haven't gotten any sound from any speaker.

Edit: Ok, Nvidia's website says my card is HDA, SPDIF as Audio Input for HDMI

You'll need the S/PDIF cable to get sound, then.

I was looking inside my case for a SPDIF out on my motherboard, I found the label for it but the closest connector to the label is a "COM1" plug. On my video card I can see a plug that looks similar to the SPDIF connections i've found looking around on the net, but I cannot see where the wire goes. Guess i'll have to open the tower up when I get home. Any tips/hints/whatever for figuring all this out so I can use this SPDIF mumbo-jumbo?

Get your exact mobo info, download the manual and you'll see exactly where the pins are. :)

Came home, found the plug on my motherboard. Found out the connector I saw on the video card was for something else, couldn't find a SPDIF output on the video card. Nvidia's website says my card has SPDIF, so naturally i'm confused. I did some more research and apparently no one knows if my card can or can't do it. Some things say the card doesn't have SPDIF, others say it's integrated into the card and you don't need an adapter. Any other ideas?
