I have been browsing the internet for a while now and seen people have alot of sound issues but none like my problem. People have been compaling about sound delay and no voices but i have no sound at all. I had a tv that was a LG and everything worked fine. But now I put my PS3 in my bedroom where i have another tv that is a samsung but the sound of the game dosent work at all but the console itself works with sound..... Someone please help me!
