Hi McDel,
To ensure your TV sound goes through your Blu-ray player, please go to Settings > Sound > Sound Output.
Also, check whether Digital Output Audio Format is set to Pass-Through by going to Settings > Sound > Expert Settings > Digital Output Audio Format > Auto.
If you continue to have issues, please give us a call at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
