What cord do I need to hook surround sound to tv?

To connect a surround sound system to your TV, you'll typically use an HDMI cable, which supports high-quality audio and video. If your TV and surround sound system both have HDMI ARC (Audio Return Channel) ports, use that for easy connection. Alternatively, you can use optical audio cables or RCA cables if HDMI isn't available. Ensure to check the specific audio outputs on your TV and inputs on your surround sound system for compatibility.
