If you've connected an external audio device, such as a soundbar or wireless earbuds, to your LG TV but hear no sound, check the cable connections or Bluetooth pairing status.
Also, use your remote to make sure the TV's audio output is set to the correct device.
Why is there no sound from my external device?
- A loose cable or incorrect connection port
- The TV's sound output isn't set correctly
- The Bluetooth device isn't in pairing mode
- A problem with the TV
How to Fix No Sound from an External Device
Step 1. Check the connection cable between your TV and the external device
- HDMI cable: Connect it to the [HDMI ARC] or [HDMI eARC] port on the back of your TV.
- Optical cable: Make sure it's facing the right way and fully plugged in.
Step 2. Check the sound output settings on your TV

FAQ
- Q. I turned on my Bluetooth device, but its name doesn't appear in the TV’s list of connectable devices.
- A. Your Bluetooth device may have automatically connected to a smartphone or tablet it was previously paired with. Turn off Bluetooth on that device, put your Bluetooth device back into pairing mode, and search for it again on your TV.
- Q. I connected my sound bar with an HDMI cable, but there's still no audio. What should I do?
- A. Make sure the HDMI cable is connected to the port labeled HDMI ARC or HDMI eARC, not a standard HDMI port. To send audio from the TV to the soundbar through an HDMI cable, you must use an HDMI ARC or HDMI eARC port.
