You can connect an external sound system to your LG TV using an optical cable connection. You only need to change the Sound Out setting of the TV to Optical Out Device.
Try This

- 2022 WebOS22 & 2021 WebOS6.0: [All Settings] → [Sound] → [Sound Out] → [Use Wired Speaker] → [Optical Out Drive].
1Prepare the optical cable.
2Check that the shape of the optical cable matches the U-shape optical plugs on the devices and connect it. If the shape is different, do not connect.
If you try to connect the optical cable with excessive force, the terminal may break.

- The steps for changing the input will vary depending on the device.
- Some devices may configure automatically once connected to the TV.
4On the LG TV, press the [Settings] button on the remote control and select [All Settings].
