You visited a shop and asked for an optical cable for the connection of your soundbar to LG TV placed in your home, office and school but when you reached home, you might be wondering what to do next? how to attach it? why optical cable? I will get your queries sorted throughout this article.
First things first
Before starting, one must plug both devices and look for all the ports available on LG TV. The port for optical fibre is very easy to find out because it is mentioned either “optical”, “Toslink” or “optical audio out”.
However, on the soundbar, it will be labelled as “optical audio input” instead of “output”.
Removing the caps
Caps must be removed before the operation because it is the most common mistake we do before connecting it that we do not remove the caps from the cables.
Connecting the wires
After identifying the ports, the next step will be to connect one side of the cable into LG TV. Insert one side of the optical cable in the TV jack where “Optical audio out” is written and the other end on the soundbar where “Optical audio input” is mentioned.
The wire on the TV side can only be inserted only in one direction while you will be pleased to know that it can be inserted in Soundbar in either direction. A tick sound can be heard.
Setting the soundbar
After joining the wires commonly the TV identifies the soundbar itself but if it does not identify it then what should we do?
- Go to TV settings
- Change the settings from “TV speakers” to “Optical audio device”
- Sound should be coming from the soundbar
However, sometimes you have to disable TV speakers to send the sound to the soundbar.
Why optical cable?
Mostly we connect HDMI cables for this purpose but sometimes many devices are connected to our TV like “set-top boxes”, consoles etc.
So an optical cable is also a good option for transferring the audio sound from TV to soundbar. However, by using HDMI we can use it for both audio and video purposes. So we need an additional cable with Optical Cable in order to send visuals.
What if TV does not have Optical Audio Input?
If the LG TV does not support optical cable we can also use HDMI ARC cable, Bluetooth, 3.5mm Aux, and RCA cable.
The best option among all is HDMI ARC cable and after that optical cable.
However, the relaying audio quality of the optical cable is better because it uses light waves to transmit signals from sender to receiver due to which better sound quality is heard.
Are only LG soundbars compatible with LG TV?
It is a common rumour that LG TV is only compatible with LG soundbars. However, it is not the fact because LG TV can send sound signals to any of the soundbars available in the market through optical cable.
Brand matching is not important in connecting the soundbars.
Cons of using Optical cable
One of the downgrades of using an Optical cable is that you do not have access to control the soundbar and the TV with the same remote.
You have to control both with separate remotes. Using two remotes can be difficult sometimes and it can also get lost easily. However, it is not a big problem.
You also need an extra cable for video transmission between the devices. Only one cable can not do the work for both audio and video.

The connection of Optical Cable to TV from soundbar is not very outraging task. It is very straightforward and one can easily do it with perfection who has some knowledge regarding technology.
In my point of view, HDMI ARC cable would be more efficient for this purpose but optical fibre will also do the job.
