Hi Bsaathoff73, Thank you for your feedback on the lip sync issues you're experiencing with your Samsung U7900F TV. This may be related to the content source, but if you're noticing the audio delay across all sources or channels, especially when using an external speaker setup (soundbar, receiver, etc.), there are a few settings that may help: 1. Adjust Digital Audio Delay. You can manually increase the audio delay to better match the video: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay 2. Enable Audio Pass-Through. Samsung TVs include an audio pass-through option, which sends the audio signal directly to your connected soundbar or receiver without additional processing by the TV. This can reduce delay when using external audio devices: Settings > All Settings > Sound > Expert Settings > Digital Audio Output Format > Pass-Through 3. Check for Firmware Updates. Ensure your TV is running the latest software, which may include performance improvements related to sound or sync: Home > left directional key > Settings > Support > Software Update > Update Now If the issue continues after these steps, please contact Samsung Support for additional troubleshooting or assistance. We’re here to help at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~Samsung Advisor
