So Ipurchased a brand new HD Smart TV hisence.when I got home I took my old TV off and hook my new TV up to my cable box. Has a great picture but no sound. I have done some research and checked my cable settings through the box made sure the audio output was on HDMI. Still no sound, so I even went as far as changing the settings with the TV. Still no sound I have contacted my cable provider Time Warner Cable and I could not figure it out either. They are sending a technician out within the next two days. I would love to solve this matter without having the technician come out. Should I just switch from HDMI going into the TV to some other plug? Can anyone help me?
