Audio on Blu-Ray disks can be quite complex. Providing very clear, multi-channel audio tracks designed to be played on high-end home theater systems.

First, look on the box for your Blu-Ray disk. In many cases, it will list the type of surround sound the movie is encoded in.
Disk encoding info bar example.

There is often a symbol showing how many speakers the audio track was designed to be played back on. Each shows a basic representation of how the audio was encoded.

2.1 Audio
This type of audio is encoded for a left and right speaker, and sometimes a subwoofer. This is the configuration provided by the stereo speakers on your television. 2.1 audio symbol.
5.1 Surround
This means the audio is encoded for 5 speakers; left front, center, right front, back left, and back right, as well as a subwoofer for base. 5.1 surround symbol.
7.1 Surround
This is encoded much like the 5.1 surround audio, but with the addition of a center left, and center right channels for an even richer immersive expirience. 7.1 surround symbol.

Your television has 2 speakers. In many cases, that means it only plays the front left and front right channels. Many movies encode the dialog, people talking, on the center channel, which does not have a speaker to play on.

If you are just using the speakers on your television, it is recommended to check the Blu-Ray menus, before you start watching, for audio options; sometimes the manufacturer will have a 2-channel audio track available so your program will sound better on the equipment you have available.

Every Blu-Ray disk has a different menu with different features, and every Blu-Ray player has a different way of accessing those menus. If you are unsure how to access the audio options menu for the specific disk you are using, check the user manual or contact the manufacturer for more information.

We must determine which platform is loaded on your LG Smart TV before beginning. Newer TVs released after 2014 will have webOS. Older models released between 2011 and 2015 will have NetCast. See the images below to help tell the difference.
