Hi George, We're sorry to hear you are experiencing issues with your M70HD TV. If you're not hearing sound from your connected device over HDMI ARC or eARC, here are some steps that can help: 1. Confirm proper port connection. Make sure you're using the HDMI port labeled ARC or eARC on both your TV and the connected device (like a soundbar or receiver). Use a High-Speed HDMI cable with Ethernet (HEC) or Ultra High-Speed HDMI cable to ensure full functionality. 2. Enable HDMI eARC Mode. Go to: Home > left directional key > Settings > All Settings > Sound > Expert Settings > HDMI eARC Mode, and set it to Auto. 3. Enable Anynet+ (HDMI-CEC). ARC and eARC require HDMI-CEC to function. Go to: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) and set it to On. 4. Adjust Digital Output Audio Format. Some receivers and soundbars may not support all audio formats. Go to: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Format, and set this to Auto if your audio device does not support Dolby Digital+ or other advanced formats. If your device does support higher formats, Pass-Through can be selected to send audio directly without additional processing from the TV. 5. Check TV firmware. Updates may improve compatibility and resolve sound issues. Go to: Settings > Support > Software Update > Update Now to install the latest version. If the issue continues, try restarting both the TV and the audio device, switching HDMI cables, or toggling Anynet+ off and back on. If you need further help, please reach out to Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available on the ‘Support’ section of our website. ~ Samsung Advisor
