Realtek High Definition Audio, "Not Plugged In," Windows 7 64bit

I've seen a few topics regarding this problem but nothing really helps, so here goes. I've got a Realtek sound card that registers on my PC as "High Definition Audio Device." My sound was working fine, but the other night I decided it was time for a reinstall. So I reinstalled Windows 7 64 bit and proceeded to reinstall all my programs and replace all my backed-up files and update windows, until I realized I still had no sound. I opened my Playback Devices and found my Speakers and Headphones to be greyed out, saying "Not Plugged In." So I Googled it and ran through a couple threads about it but like I said, nothing really seemed to work. I tried to go to Realtek's site and get the latest High Definition Audio driver, I tried to uninstall the current driver and reinstall with the latest, I tried new speakers, but to no avail. If anyone could give me a nudge in the right direction I'd greatly appreciate it.

    Hi,

    ·          What is the model number of the sound card?

    ·          What is the status of the sound card in device manager?

    Step 1: Try the steps in

    Step 2: Also update the chipset/BIOS with the latest drivers/firmware from the manufacturer’s website.

    NOTE: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    So, after reviewing many posts, i just unplug and replug back in the video/audio cable that goes from my plasma to the back of the computer (hd4350 card).  It's a pain in the "you know what" to do that each time, but it at least works.
