Hi, Thank you for purchasing Samsung's Q80D TV and for your feedback on the sound. To ensure you’ve got the latest sound quality updates, please confirm that your TV is up to date with the latest firmware version. You can check by going to: Home > Menu > Settings > Support > Software Update. If the sound is still not to your liking after updating firmware, there are several sound settings you can adjust to suit your personal preferences. • Sound Modes may better meet your personal preferences. Go to: Menu > Settings > All Settings > Sound > Sound Mode, or Expert Settings to fine-tune and customize your sound. • Adaptive Sound will also further optimize sound quality by analyzing the viewing space and the acoustic components of the content. Go to: Menu > Settings > All Settings > General & Privacy > Intelligent Mode Settings. Should you choose to add a Samsung Soundbar to your TV, please know that our Q-Series Soundbars (such as the HW-Q600C) feature Q-Symphony which will synchronize with the speakers of your TV for an immersive 3D sound experience. To assist you with possible sound settings adjustments for a better audio experience or choosing a Samsung Soundbar to complement your viewing enjoyment, please reach out to us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. ~ Samsung Specialist
