1. Check if the external speakers are properly connected to your Smart TV

Make sure the wires are properly plugged into the ports and that your TV input is set to the proper source.

2. Look through the on screen settings menu

Make sure the TV is set to output the sound through the external speakers rather than connected headphones or a different device.

3. Check for any software updates.

Old software versions can limit the capabilities of your Smart TV, like preventing sound from playing through external speakers.

4. Reset the audio settings.

If you recently rearranged any of the audio settings, you may need to reset them to their default state for sound to play properly.
