Hi Jaksun, We appreciate you sharing details of the sound issue you’re experiencing on your DU7200 TV. There are a few troubleshooting steps I recommend trying: 1) Please check the volume control of your TV, and then check the volume control of any external devices (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between any external device and the TV and then try the cable connection again. 2) Set Sound Output to the TV Speaker by going to Settings > All Settings> Sound > Sound Output. 3) Check whether Digital Output Audio Format is set to Pass-Through by going to Settings > All Settings> Sound > Expert Settings > Digital Output Audio Format > Auto. I hope this helps. Should your issue persist, please contact Samsung Customer Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. Our LiveChat agents are also available by clicking on the ‘Support’ link on our website. ~ Samsung Advisor
