How to Control LG Soundbar with TV Remote
If you want fewer remotes on the coffee table, the easiest solution is to make your TV control the LG soundbar.
This guide explains the exact settings, connections, and compatibility checks that make volume and power control work reliably.
LG soundbars support several control methods through HDMI ARC, eARC, optical connections, infrared, Bluetooth, and TV-brand universal remote features.
The best approach depends on your TV model, your soundbar model, and how you connected the devices.
What makes TV remote control work with an LG soundbar?
TV remote control usually works in one of three ways: HDMI CEC, IR learning, or a TV’s built-in external speaker control system.
For LG soundbars, HDMI ARC or eARC is usually the most dependable option because it lets the TV send volume commands directly to the soundbar.
- HDMI ARC/eARC: Best for volume, power, and input switching on many TVs.
- Optical cable: Works for audio, but remote control often requires extra setup.
- Bluetooth: Good for wireless audio, but not always ideal for remote volume control.
- IR learning or universal control: Useful when HDMI control is unavailable.
Use HDMI ARC or eARC for the simplest setup
HDMI ARC (Audio Return Channel) and eARC (enhanced Audio Return Channel) are the most common ways to control an LG soundbar with a TV remote.
These features let the television send audio back to the soundbar over the same HDMI cable while also passing control commands through HDMI CEC.
LG calls its HDMI-CEC feature Simplink.
Other brands may use names such as Bravia Sync, Anynet+, VIERA Link, or CEC.
Even if the TV and soundbar are from different brands, the CEC standard often still works.
Setup steps for HDMI ARC or eARC
- Connect the TV’s HDMI ARC/eARC port to the LG soundbar’s HDMI OUT (TV ARC) port.
- Enable Simplink (HDMI-CEC) on the LG soundbar if available.
- Turn on HDMI-CEC or the brand equivalent in the TV audio settings.
- Select the sound output as External Speaker, HDMI ARC, or Receiver, depending on the TV menu.
- Test volume using the TV remote.
If the setup is correct, the TV remote should raise and lower the soundbar volume and may also power the soundbar on and off with the TV.
How to control LG soundbar with TV remote using optical cable
An optical cable can deliver clean digital audio, but it does not carry HDMI-CEC commands.
That means volume control may not work automatically unless your TV or soundbar supports a separate remote-control feature.
Some LG soundbars support TV remote control through their settings menu, even on optical input.
In many cases, this involves enabling an IR function or using a learning mode that lets the soundbar recognize your television remote.
What to check with optical connections
- Make sure the soundbar input is set to Optical.
- Check the LG Soundbar app or onboard settings for TV remote or remote control options.
- Confirm that your TV remote uses infrared, not only Bluetooth.
- Replace weak remote batteries, which can cause intermittent commands.
Optical is still a solid audio connection, but if your goal is seamless control, HDMI ARC is usually better.
Use your TV’s universal remote or device setup menu
Many modern TVs can be configured to control external audio devices, including LG soundbars.
This is often the path to follow when HDMI ARC is unavailable or when the TV remote does not immediately adjust soundbar volume.
Depending on the TV brand, the process may be labeled Universal Remote, Device Connection, External Device Manager, or Audio System Setup.
The TV may ask for the soundbar brand, model, or connection type.
Typical universal remote steps
- Open the TV settings menu.
- Find universal remote or external device setup.
- Select soundbar or audio system.
- Choose LG as the brand if prompted.
- Follow the on-screen pairing instructions.
Some TV platforms can learn a specific remote profile for LG devices, which can improve volume response and power control.
If the menu fails to detect the soundbar, recheck the physical connection and power cycle both devices.
LG soundbar settings that affect remote control
Several LG soundbar settings can affect whether the TV remote works correctly.
If control is unreliable, the soundbar may not be configured for external command input.
- Simplink: Enable this for HDMI-CEC control.
- Auto Power: Turns the soundbar on with the TV when supported.
- TV Sound Sync: Useful on some LG TVs for synchronized output and control.
- Input mode: Make sure the soundbar is on the same input as the TV connection.
LG also offers companion apps on some models that can help confirm current firmware, input status, and control features.
Keeping firmware current may improve compatibility with newer televisions and remote protocols.
Why the TV remote controls volume but not power
A common issue is that the TV remote adjusts volume but does not turn the soundbar on or off.
This usually means audio control is working, but the power command is not being passed through the connection.
Possible causes include disabled HDMI-CEC, a TV power-saving setting, an incompatible input mode, or a soundbar feature that blocks standby behavior.
In some cases, the TV sends volume commands through CEC but only powers devices it recognizes as fully paired.
Fixes to try
- Turn HDMI-CEC off and back on in both devices.
- Restart the TV and soundbar after changing settings.
- Reconnect the HDMI cable to the ARC/eARC ports.
- Update the TV and soundbar firmware.
- Test with another HDMI cable certified for ARC or eARC.
Common problems and quick fixes
When the TV remote does not control an LG soundbar, the issue is usually configuration rather than hardware failure.
Start with the basics before replacing cables or resetting devices.
- No volume control: Confirm ARC/eARC, Simplink, and HDMI-CEC are enabled.
- Volume works intermittently: Replace remote batteries and check for signal obstructions.
- Wrong audio output: Set the TV to external speakers or audio system mode.
- Soundbar not detected: Reboot both devices and unplug power for 30 seconds.
- Optical setup has no control: Use TV remote learning or switch to HDMI ARC if possible.
How TV brand differences affect LG soundbar control
The exact setup depends on the television manufacturer.
Samsung, Sony, TCL, Hisense, Panasonic, and LG TVs all present menus differently, even when the underlying HDMI-CEC behavior is similar.
For example, an LG TV may use Simplink and TV Sound Out settings, while a Samsung TV may rely on Anynet+ and Audio Receiver.
Sony TVs may expose Bravia Sync options and separate audio system pairing.
The key is to identify the TV’s CEC feature and enable it alongside the correct sound output.
Best practices for reliable daily use
Once your LG soundbar is working with the TV remote, a few habits can keep it stable.
These are especially useful if you switch inputs often or use streaming devices like Roku, Apple TV, Fire TV, or game consoles.
- Use HDMI ARC or eARC whenever possible.
- Keep the TV and soundbar firmware updated.
- Avoid mixing multiple control methods unless necessary.
- Plug streaming devices into the TV, not the soundbar, unless required for audio passthrough.
- Label the correct HDMI ports to avoid accidental reconnection to the wrong input.
With the right cable, the right settings, and a quick device restart, most users can make the TV remote handle LG soundbar volume with minimal effort.
