LG's smart TVs can be connected to a sound device via an optical cable. The brand's televisions feature an optical output so the audio is directed to a home theater, receiver, soundbar, among other devices with compatible sound input. The connection is a good alternative in more modern systems, which use HDMI ARC technology to transmit audio and video.
After properly connecting the cable to the devices, it is necessary to access the audio settings in the webOS menu to activate the optical output. In this way, with the sound system connected and configured correctly, the sound is recognized and reproduced with greater power. Check out the following tutorial on how to use a sound system connected to the LG smart TV by the optical cable.
