The embedded sound hardware on the motherboard may de defected. Without the appropriate test equipment it would be difficult to diagnose. At a minimum inspect, reset all the cards along with cleaning the gold contacts.
Afterwards reload the OS.
Or salvage independent sound card, plug and play. Posted from my iPhone/Mobile device

I had a spare sound card. I installed that on the Antec and now I have sound. I will do the same for the other one.
Thanks for all of your help! You guys are the best!
