Check the volume level and ensure the TV is not muted. Also, verify that the audio output settings are correctly configured for your external speakers or sound system.

For the best movie experience, use the 'Cinema' or 'Movie' picture mode, which typically offers a warmer color temperature and enhanced contrast.
To enable parental controls, go to Settings > Safety & Restrictions, where you can set up content restrictions and PIN protection.
Ensure that the content you are playing is in 4K resolution and check that your HDMI cables are rated for 4K. Additionally, verify that the input source is set to a 4K-compatible device.
Connect external devices using the HDMI ARC or optical audio port. Then, go to Settings > Sound to select the appropriate audio output.
