Almost all LG TVs manufactured after 2009 come with HDMI ARC. Here, ARC means Audio Return Channel. However, some users face LG TV HDMI ARC no sound problem which needs to be solved. But what causes it?

There can be several reasons for LG TV HDMI ARC no sound problem. The most common one is that you are not using an HDMI cable that supports ARC.

In this article, I am going to talk about all the different reasons and point to the solutions. Without further ado, let’s get started. 

What Is HDMI ARC on LG TV?

HDMI ARC on your LG TV works the same as other HDMI ports with some additional benefits. It allows the TV to communicate with other sound outputs and gives you the control using a single remote controller. 

For the best quality sound, you must not rely on the built-in audio system of your TV. It is true for all brands.

Now, installing an additional soundbar can introduce more cables and extra remote control.

With HDMI ARC, you can eliminate that problem as the television can send the audio signal through this special HDMI port.

Nowadays, most TVs come with this port as it has become a standard practice across the industry.

Does My LG TV Have HDMI ARC?

One very quick and simple way to know whether your LG TV has HDMI ARC or not is by looking at the ports. If your LG TV has it, you will see ‘ARC’ written on a specific HDMI port and others don’t.

Moreover, LG televisions manufactured after 2009 come with ARC ports. But not all models have this feature.

In recent years, the scenario has changed and all LG TVs come with HDMI ARC as a standard.

Why Is My HDMI ARC Not Working on LG TV?

The troubleshooting of the problem starts with checking the compatibility of devices and cables.

First of all, make sure that your LG TV has an HDMI ARC port. I have already told the way to make sure of that in the previous section.

Then, check the HDMI cable you are using. Not all cables support HDMI ARC.

At the same time, you should use soundbars that are compatible with ARC features.

If everything is in order, the ARC will work. If not, then you will have to adjust some settings. Let me tell you how to fix the problem in the next part.

Step 2: You will see Settings in the launch bar where you have to navigate to the sound menu.
