What Is an Optical Cable?

So, before moving straight to the steps why not first learn more about optical cable, shall we? Well, Optical cable port is often neglected as but it one of them which really stands out. Most of the cables we use in our media system use electrical signals. It is either digital or analogue. Be it the ARC Cable or HDMI Cables, all of them have wires inside but when it comes to optical cables it is something different.

The optic cables use laser light to transmit audio signals between the devices. It was introduced back in 1983 by Toshiba for their Compact Disc Players.

Mostly in old televisions, the HDMI ARC (Audio return channel) port is missing which is required to connect the soundbar to television. If you own one of those TV then the Optic cable is a great choice. So, now that we have learned enough about it, let’s check out how we can use it to connect the soundbar.

After doing this, if the sound is still not coming out of the soundbar then check if the inbuilt audio from the speaker is turned off or not. This will make sure that the sound is directed toward the digital audio out port.
