Here are some things to try if you’re experiencing sound problems on your Smart TV:

1. Make sure your volume isn’t set too low or muted on your TV and any external device.
2. Go to your TV audio menu and make sure the correct sound profile is selected.
3. Verify all cables are securely connected between the TV and any device.
4. Try a different source device, such as a different streaming platform or cable.
5. If you are using headphones on the TV, make sure the headphone jack is properly functioning.
6. Turn off automated audio enhancement options if they are activated on your TV.
