I know that the GTX 560 TI supports 7.1 surround sound, but I can't get it to work. I have the latest Nvidia 280.26 drivers installed. When I go into Control Panel > Hardware and Sound > Sound, I have four playback devices available: LG-TV1 (HDMI connection from the 560 to the TV); Speakers (which I have my Turtle Beach 7.1 headphones connected to); Realtek Digital Output (for digital coax S/PDIF connections); and Realtek Digital Output Optical (for optical S/PDIF connections). If I right-click on LG-TV1 and select Configure Speakers, it allows me to select Stereo - nothing else (see first image below). If I select Configure Speakers when right-clicking on Speakers then I have the option of Stereo, Quadrophonic, 5.1 Surround, and 7.1 Surround (see second image below).
The way I have my PC set up is with an HDMI cable from my PC to my TV, and then a digital coax from the TV to my Onkyo receiver. Pretty straight forward, or so I thought. I can get stereo output with this configuration, but nothing more. I tried to change the default Sound output to Speakers but I can't get any sound to come through (perhaps this option is to be used with the HDMI port in the motherboard?). I connected an optical TOSlink cable to the S/PDIF port on the motherboard and connected it directly to my receiver, but I'm not getting any sound that way either (perhaps the HDMI connection from the 560 is disabling the S/PDIF connection?). I then connected HDMI from the 560 to the receiver directly, then another HDMI out from the receiver to the TV; still, no audio. I even connected DVI from the PC to HDMI on the TV, just in case the HDMI from the GPU was cancelling the optical out; of course, that didn't work either. So far, the ONLY way to get audio is with HDMI from the 560 to the TV, then digital coax to the receiver, but being limited to stereo is less than satisfactory.
FWIW, this is a brand new PC build. I made a gaming HTPC with the Galaxy GTX 560 TI, i7 2600, DH67GD Intel motherboard, 8GB RAM, etc. My old PC had a 9800 GT so I used DVI to HDMI for video, and digital coax from the motherboard to the receiver. I much prefer digital coax over TOSlink just because the latter always seems to fall out so easily. Alas, my H67 mobo doesn't have digital coax S/PDIF so I'm trying to make the most of what I have.
What am I doing wrong? Why don't I have more speaker configurations available with the 560's HDMI connection? Is HDMI from the 560 blocking the optical S/PDIF connection?

Dude have you sorted this one out?
Your problem is that you have gone from PC to TV (stereo only in your case) to Onkyo receiver.
What you need to do is PC - HDMI to receiver - then HDMI from receiver to your TV. If your receiver doesn't support HDMI inputs & HDMI outputs then your screwed unless there is some magical splitter out there somewhere
I have learned a lot over the last two days, with the same problem, similar setup.
I have a Gainward GTX560Ti 1024Mb , running a HDMI1.4 cable to my Samsung LED LCD TV, then Digital Audio cable to my Yamaha Audio Video Receiver(AVR). 5.1 surround speakers attached to that. As the original poster showed in the diagrams, windows isn't showing an option for the surround speaker setup that i theoretically thought i should be able to have.
not the case apparently.
As someone nicely explained over HERE you can try to run the HDMI cable to the AVR first then HDMI to the TV. provided of course your AVR will split the sound into the speakers then video into the TV, or the TV supports Audio Return via HDMI cables.
I tried it, unfortunately my AVR/TV isn't up to scratch , and even with a digital audio cable running back to the AVR from the TV, still got no 5.1 (any sound actually) speaker sound.
As someone also mentioned HERE you may need to actually get a sound card, running with DD Live or DTS, first then have a separate audio cable to the AVR.
hope this helps anyone else who's also spent a lot of searching online looking for a solution!
