Better TV sound
Thin TVs have tiny speakers. Settings help; external speakers help more.

Try the settings first
- Turn on dialogue or voice enhancement if voices are hard to follow.
- Use night mode to reduce loud explosions late at night.
- Turn off virtual surround if it makes voices hollow.
Soundbars
A soundbar connected to the TV's HDMI ARC or eARC port lets one remote control the volume. A model with a separate subwoofer adds real bass; a centre channel keeps dialogue clear.
Placement
Put the soundbar directly below the screen, not inside a closed cabinet, so sound reaches you rather than the shelf.
