    I want to get 5.1 surround sound from my PC using my 5.1 home theater system but I couldn't figure out what sound card to buy and what kind of cables, output and inputs to use to connect it to my receiver. I'm kinda lost and I'd appreciate any help.

    Here's the backside of my receiver:

    Does this receiver support true 5.1 input? It supports DTS-HD and Dolby TrueHD/DigitalPlus/ProLogic II.

    What kind of sound card should I buy? (my on-board sound card doesn't support surround sound)

    What kind of connection should I use? What output from sound card to what input on receiver using what kind of cable?

    I'd appreciate any guidance.

    I'm not a sound pro, but shouldn't optical work?
    If it does, some mainboards have the same optical out, a soundcard will have one I guess? But more experienced gurus should really help on this one.

    Yeah optical will work for lossy 5.1
    Thing to note, passthrough will be fine for movies, and music, but for games, you'll need a soundcard that supports DTS Live/DD Connect.

    For 5.1 uncompressed PCM, use a HDMI connection from a free port on your graphics card, or laptop. You don't need to connect a monitor, and you can just have Windows mirror your desktop to the new display, to keep you from tracking the mouse to the unused display.

    Don't bother with optical, HDMI will pass the same bitstreams but also support PCM 5.1 (Optical doesn't)

    Graphics card > Reciever > TV

    Will this be true 5.1 or something fake like 2+2+1?

    I tried GPU->HDMI->TV and it only does Stereo, no option for surround on output device (Nvidia) settings. I also tried PC->HDMI->Receiver->HDMI->TV but that also turned out only Stereo.

    the receiver has AMP+TV set, so its passing TV stereo capabilities,
    That looks like the back panel of a sony unit, which model?

    It'll be lossy 5.1 yes, proper discrete channel passthrough.

    Using HDMI to your receiver, it will be capable of doing up to 7.1 PCM lossless. You need to configure Windows Audio that it's 5.1 or 7.1, else it will default to Stereo. It can also passthru encoded surround to the receiver if it can decode it.

    Does lossy mean loss of sound quality? How much lossy would it be, negligable or quite drastic?

    There was no option in Windows sound settings or driver software configuration for 5.1. There was only Stereo option. Do you think it's a driver problem and there should be an option or HDMI->receiver->TV setup?

    When I say lossy, I mean no HD codecs such as Dolby TrueHD. But Dolby Digital and DTS will work, which is fine.

    Assuming you set up the receiver with a proper 5.1 setup, there should be a 5.1 option in the Windows Config. Settings...Sound...HDMI Audio Device ... Configure

    I've tried this before but I've only have Stereo as option, no surround.

    I didn't see such setting. There is a Audio mode that says Auto and Bitstream, is that it?

    Windows might not detect the surround capabilities if it's running before the AV. Have you tried having the PC off and the AV on, then turning the PC on, cold boot?
