Nunya Biz, Thank you for sharing your thoughts regarding the DU6900 TV’s sound quality. We recommend adjusting the Sound Settings to improve your experience. You can change the Sound Mode by going to Settings > All Settings> Sound > Sound Mode. You can also customize the sound with Expert Settings by going to Settings > All Settings> Sound > Expert Settings. To address the audio delay, you may want to try the Audio Pass-Through feature. This feature allows the audio signal to be sent out unprocessed to an external Soundbar or receiver connected to the TV. The external Soundbar or receiver then processes the audio, thereby eliminating the added step of processing by the TV, which adds delay. To activate this feature, go to Settings > All Settings> Sound > Expert Settings > Digital Output Audio Format > set to Pass-Through. You can also purchase an HDMI to Optical Converter to pair your stereo system directly to the TV via cable. If you need further assistance, we would be happy to help! Please feel free to contact Samsung Support at 1-800-SAMSUNG, available from 8 AM to 12 AM EST, seven days a week. You can also chat with us on Samsung.com for immediate assistance. ~Samsung Pro

Hi there, Thank you for reaching out and letting us know about the Closed Captioning issues you are experiencing with your DU6900 TV. Please know that most Streaming Apps have their own Settings for Closed Captioning. Go into each app and locate the settings icon to enable Closed Captioning. To access all other Closed Captioning Settings, go to Settings > All Settings> General > Accessibility > Caption Settings. The DU6900 TV offers 2 HDMI ports and is Bluetooth and Wi-Fi capable, allowing a seamless connection across multiple devices at a time. If your external device requires an Optical port, we recommend utilizing an HDMI to Optical Converter. These can be found at your local electronics store. Please also keep in mind that an Optical port can be found on our DU8000F Series and above. If you need further assistance, we would be happy to help!
