Since I can't guess what cable system you're on and almost all here use cable boxes, the setup is theirs, not the TV.
I cannot find "Set Up" in menu. I'm trying to troubleshoot audio and my cable company wants me to click on Menu - Set Up - Audio track to see if English is the default. I can't find anything under Menu that leads me to the Set Up or audio track default. I have a Samsung 6000 series Smart TV (3D).
