SLnelson, Thank you for sharing your experience with volume fluctuations. Please try the following which may help resolve this: 1. Turn off the Sound Sensor switch by using the button at the bottom of the TV, beneath the Samsung logo. With the TV on, you can push the button to the left to turn the sound sensor on or to the right to turn it off. 2. Try disabling some of the TV's intelligent functions, as these will automatically analyze and adjust your sound which may cause your volume to fluctuate. Go to Settings > All Settings > General & Privacy > Intelligent Mode Settings and select Intelligent Mode to turn off all the functions or select each option to turn it off. 3. Please also make sure your TV’s firmware is updated. You can check this by going to: Menu > Settings > Support > Software Update. I hope these tips help. If you need further assistance, please reach out to Samsung Support at 1-800-SAMSUNG, 8AM - 12AM EST, 7 days a week.
