The TV can only output a 2 channel signal from the analog audio output. If your HTS has a surround mode to synthesize surround such as Dolby ProLogic select that.
The TV optical output may support surround sound. Check the TV menu to see if it does. You may have to turn it on and turn the TV speakers off to get it to work.
The optical connection will usually be superior in sound quality as well.
