I found out what the problem is but i'm not sure which cable to get. My TV manual says 'Connect a D-Sub cable between PC IN [PC] connector on the TV and the PC output connector on your computer" (did that part <<) and then "Connect a PC Audio Cable between the PC IN [Audio} jack on the TV and the Audio Out jack of the sound card on your computer. . The port is next to the VGA cable in the pic. More pics on bottom.
