Hi JayJay, Thank you for sharing your experience with volume fluctuations on your Samsung U7900F TV. Sudden changes in volume can often be related to audio settings or content differences between sources or apps. Please try the following adjustments to help stabilize your TV's audio: 1. Enable Auto Volume. Go to: Settings > All Settings > Sound > Expert Settings > Auto Volume. This feature helps maintain a consistent volume level when switching channels or apps. 2. Change Sound Mode. Try a different sound mode to see if one offers a more stable output: Settings > All Settings > Sound > Sound Mode (We recommend Standard or Amplify for more even performance.) 3. Check External Devices. If you're using a soundbar, receiver, or other audio device, check that its volume leveling or dynamic range settings aren’t interfering with the TV’s audio. 4. Update Firmware. Ensure your TV is running the latest software, as updates may include audio improvements: Settings > Support > Software Update > Update Now If the issue persists after these steps, please don’t hesitate to reach Samsung Customer Support at 1-800-SAMSUNG, 8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun. LiveChat is also available via the ‘Support’ link on our website. ~ Samsung Advisor
