Hi Suzie1019, Thank you for sharing your thoughts regarding the DU8000 TV’s sound quality. We recommend adjusting the Sound Settings to improve your experience. 1) You can change the Sound Mode by going to Settings > All Settings> Sound > Sound Mode. 2) Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to Settings > All Settings> Sound > Expert Settings > Auto Volume. You may also want to ensure you are running the latest Firmware. Go to Settings> Support> Software Update. If you’d like more help with settings, we are always happy to help! Call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
