I have a pc with no surround sound on the motherboard. On that pc is GTX 560 Ti graphics card that I connected to my tv through HDMI and then ran the audio out to my Yamaha RX-V673 receiver via optical cable. This produced perfect picture quality and good sound when I only had two speakers and a bass. Now however I have a 7.1 system and my PC isn't recognizing it. In the sound settings it shows my LG tv and only allows me to choose stereo. However if I run my computer through my reciever via HDMI and then into my tv via another HDMI it does recognize the 7.1 set up. The problem is the video quality tanks. At first the whole screen wouldn't even fit on the TV and only after I adjusted it via the Graphics cards software. Even changing things on that I can't get it to look half as good as it used to when the video went straight from my computer to the TV. Now I'm stuck between quality video or surround sound. Please help.

if your motherboard has realtek sound chipset in the realteck sound manager the default is speakers. pull the tab down to 5.1/.7.1. the same set up should be under windows sound manager control panel. it defaults to two speakers. make sure it set to 7.1/5.1 sound on the digital audio output port if your mb has one.

It doesn't, and I've been researching them all over and most people say the digital out only supports stereo so I don't want to get one and then have it only work through two anyway. Also most cards I find are only 5.1 not 7.1 and the 7.1 cards out there are either crazy expensive or super cheap. I need a PCIe card with not much size as the majority of the space is taken up by my video card.

The TOSLINK (Optical) port is capable of only stereo in lpcm or to carry encoded dolby digital content. HDMI on the other hand can carry upto 8 channels of pcm data. If your av receiver has the option to disable processing (enable direct passthrough) this might solve the tank in video quality. Alternatively you can run a dvi to hdmi converter and use that to hook your tv up and the hdmi port on your graphics card for the receiver. Hope this solves your issue :) To further define your setup for processed audio, you would have to open windows sound panel, choose your receiver, click configure and define the number and position of your speakers.
