Ok, so for christmas I got a FUNAI HD TV, and I recently hooked up a old dell pc to it. Now its not a huge deal cause my dell is a backup pc but I also use it to play older games but anyway, the sound will not come out of the tv speakers but when I plug my headphones into the tower the sound works fine. Do I need seperate speakers for the sound to work? I figured I could get the sound to come out of the tv but no luck so far. Any ideas?
