ebarr59, Thank you for sharing your experience with volume fluctuations on your TV. This is likely due to a setting you may have accidentally enabled. Here are a few steps that may help resolve the issue: 1. Turn off the Sound Sensor: Use the button located beneath the Samsung logo on the bottom of the TV. With the TV powered on, press the button to the left to turn the sensor on or to the right to turn it off. 2. Disable AI Sound Features: Some AI functions automatically analyze and adjust sound, which may cause volume to fluctuate. To disable these: Settings > All Settings > Advanced Features > AI Mode Settings > AI Mode. You can turn off all AI functions at once or toggle each setting individually. 3. Check for Firmware Updates: Keeping your TV up to date may improve audio performance: Settings > Support > Software Update > Update Now To help stabilize audio, please do enable Auto Volume, which automatically adjusts sound levels when switching inputs or channels: Settings > All Settings > Sound > Expert Settings > Auto Volume > On (please note: Auto Volume can be used with TV speakers only, not with connected audio devices) If you'd like more assistance, please contact Samsung Support for further assistance at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat and additional support resources are also available through the Support link on our website. ~ Samsung Specialist
