LG soundbars are stereo speakers designed to connect to televisions for better audio performance. An LG soundbar can be hooked up to an LG TV by connecting the two units via the included optical cable or HDMI cable.

However, there are many different combinations of the two units to make the soundbar work well. To connect an LG soundbar to a television, you need to know the exact types of cables included with the soundbar and how they are used.

This article will help you how to connect LG soundbar to TV and play music.

Ways of Connecting Soundbars to LG TV

Connect Soundbar to LG TV With HDMI

HDMI is the most common and easiest way to connect soundbars to TVs. It is faster than other connections and can transmit large amounts of data. HDMI cables can also support high-resolution audio formats such as Dolby TrueHD or Dolby Atmos.

HDMI-ARC support is required for your LG TV to pair your soundbar with your TV via HDMI. ARC stands for Audio Return Channel, which means that the cable can transmit audio in both directions.

Turn on your TV and soundbar first. Next, connect the cable to one end of your soundbar’s HDMI OUT port. Then, connect the other end of the cable to the HDMI IN port (ARC) on your LG TV.

HDMI ARC allows you to pair additional components, such as Blu-ray players or PS4s, to your soundbar. It connects to your LG TV via one HDMI cable.

Although not all TVs come with an HDMI ARC port, there are still other options that you can use to link your TV and soundbar.

Wireless Connection Of Soundbars to LG TV

LG Sound Sync is a feature that some LG TVs offer. It allows you to wirelessly connect a soundbar or home theater system to your LG TV.

You can set it up by pressing the Home Button on your LG TV Magic Remote. Select Sound, then Sound Out. Next, change the audio settings to TV Speaker and LG Sound Sync Wireless.

After you have pressed Device Selection, your LG TV will begin searching for compatible devices. In this instance, it is your soundbar. Next, press the LG TV button on the remote control. The name of the soundbar will be displayed on the screen. You can then select it and pair your TV and soundbar.

Here are the best RCA soundbars for separate audio and video relay audio.

Digital Optical or Digital Coaxial

A digital optical cable or coaxial cable can connect soundbars and TVs that do not support HDMI connections. Although it won’t transmit higher-end audio formats like 5.1 surround sound, it can still be used.

A digital optical cable and a coaxial cable are slightly different. The connector on the optical cable port is square, unlike the coaxial’s circular connector.

Optic connections convert the electrical signal into optical light and then return it to electrical when it reaches another end of the cable. This reduces interference even more than HDMI and can pass a higher resolution of video and audio signals.

Connect an LG TV to your soundbar with your digital audio cable. Pair the other end of the cable to the Optical OUT (or Digital Audio IN) port on your LG TV. Next, change the source of the soundbar to D.IN.

Before you buy any cables, make sure to search and check the connections on your LG TV.

3.5mm Line Out Or RCA Cable

You can still pair your soundbar using the 3.5mm line-out or RCA even if HDMI, wireless, and optical audio input connections are unavailable. This relays analog audio only and not digital.

Connect a soundbar to your TV by connecting the 3.5mm cable using the line-out port. Connect the other end of the cable to the soundbar.

3.5mm Line Out Or RCA Cable

On the other hand, RCA sockets are the red and blue connectors that older-school components and TVs usually use. This step connection is simple: pair the white connector to a white output socket, and the red connector the red socket. This applies to both the TV and soundbar.

We recommend the wireless speaker kits for your system to maintain a high-quality audio transmission but without affecting the Sound or using RCA.

Headphone Jack

The headphone jack can be used to connect LG soundbar and your LG TV. However, we recommend it only if you don’t have any other options.

You can change the function of the headphone jack to a line-out on some TVs. This allows you to set the sound settings without having to adjust them. You will need to adjust your TV’s volume, bass, and treble levels if it doesn’t offer this feature and control sound effects.

Many soundbars, especially those with higher-end features, offer different settings and options to enhance the Sound.
