LG Soundbar Keeps Cutting Out – [Fixed in Easy Steps]

1. Refresh the Soundbar Connection

The LG soundbars support wireless (Bluetooth) and wired (HDMI/Optical) connections and can be connected via both simultaneously.

The persistent audio cutting may be a result of a fluctuating Bluetooth connection or an issue with the physical wired LG soundbar connection.

Here’s how to reconnect the LG soundbar’s audio cable or Bluetooth properly!

  4. Reconnect to the LG soundbar from the Bluetooth settings.

How to Reconnect LG Soundbar From HDMI/Optical?

  2. Unplug the other end of the cable from the LG soundbar’s back.
  3. Next, wait for 60 seconds while the audio jack is disconnected.
  4. Ensure the soundbar is set as the default device in the settings.
Important: Verify the wireless device is within range of the soundbar to pair over Bluetooth!

2. Hard Reset the LG Audio Devices

There could be an issue with the LG soundbar or subwoofer’s connection, resulting in persistent audio cuts and interruptions.

Hence, a strongly effective step with the potential to address all the underlying issues with your equipment is to perform a hard reset by discharging the hardware.

Here’s how to perform a hard reset on both LG audio devices easily!

How to Hard Reset the LG Soundbar?

  1. Press the “On/Off” button on the soundbar’s upper panel.
  2. Release the button after the soundbar’s LED lights go off.
  3. Unplug the power adapter of the device from the power.
  4. Wait for 60 seconds while the LG soundbar is discharging.
  5. Reconnect the power cable of the device back into power.

How to Hard Reset the LG Subwoofer?

  1. Disconnect your subwoofer’s power cable from the outlet.
  2. Unplug the other end of the cable from the subwoofer’s rear.
  3. Wait for 1 minute while the subwoofer is actively discharging.
  4. Reconnect the power supply wire and test the LG subwoofer.
Note: If the subwoofer blinks in green, shows red or the LED lamp is off, ensure the power cord is secure, otherwise your audio may be cut out.

3. Adjust the Soundbar’s “Sound Effect”

All LG soundbars have an integrated “Sound Effect” function, offering up to 6 individual sound modes of the equalizer.

Pressing the sound effect button on your remote control cycles forward through the sound effects, one of which may be causing the cutting out audio on your soundbar.

Here are the available sound effects on the soundbar and the specifications of each:

  • Standard” – Optimizes the soundbar’s audio for any type of content.
  • Cinema” – Optimizes the soundbar’s output audio for movies/shows.
  • Clear Voice III” – Boosts the output audio clarity of the LG soundbar.
  • Spots” (Football/Cricket) – Optimizes the audio for any type of sport.
  • Music” – Adjusts the audio of the LG soundbar for listening to music.
  • Game” – Adjusts the audio of your soundbar for gaming or gameplay.

After specifying a sound effect, it will appear on the soundbar’s display and disappear shortly.

You will be unable to view what’s the current mode unless pressing the “Sound Effect” button again to cycle through the options again.

4. Move Away From Interfering Devices

The cutting-out issue with the LG soundbar can be addressed by dislocating interfering devices that can potentially impact the wireless signal of the soundbar or the subwoofer. 

The LG soundbar can be particularly vulnerable to interference if connected wirelessly, over Bluetooth rather than HDMI or Optical cable connection.

Here are devices that can interfere with the soundbar:

  • Network units of any type (modems, routers, or gateways.)
  • RF transmitters, such as radios, baby phones, or doorbells.
  • Any devices emitting Bluetooth signals of similar frequency.

So, to ensure nothing interferes with the LG soundbar or subwoofer, verify there are no wireless devices within a 20-foot range from the soundbar’s position. 

Note: Avoid placing objects with metallic/reflective surfaces near the LG soundbar or subwoofer!

5. Unpair & Reconnect the Subwoofer

If the output audio or the LG soundbar bass keeps cutting out, another proven solution would be to reset the subwoofer signal transmitted by the soundbar.

For this purpose, you must unpair all the connected audio devices from each other and then wait for the connection to finish resetting.

Here’s how to disconnect the LG soundbar from the LG subwoofer easily:

  1. Hold the “PAIRING” button on your subwoofer’s back.
  2. Next, release the button after holding it for 15 seconds.
  3. Unplug the power cable from the back of the subwoofer.
  4. Wait for 60 seconds and reconnect the LG unit to power.
  5. Then, hold “PAIRING” to reconnect it to the LG soundbar.

One More Thing: Place the Subwoofer Closer!

The subwoofer’s audio may be cutting out if the device is placed too far away from the soundbar and the wireless connection has weakened.

To ensure both devices support reliable connection, place the subwoofer within a 10–15 feet range from the soundbar.

Tip: Keep testing the subwoofer’s bass performance while picking a new location!

6. Update the Soundbar’s Software

You can resolve existing faults with the LG soundbar’s audio by updating the software build to the latest version.

So, updating the soundbar’s OS is possible through the LG Soundbar app available for Android and iOS mobile devices, which can resolve the cutting-out issue quickly.

  3. Go to “[Settings]” → “[Software Update Notification]” to enable.
  4. If a new notification pops up, tap the message and follow the steps.
Notice: If the update fails or the download is unsuccessful, check the mobile’s connection!

7. Force an LG Soundbar Factory Reset

If you’re still unable to improve the LG soundbar’s sound output performance, perhaps the best resolution is to conduct a full system reset.

However, note that the LG soundbar’s network and audio settings will be reset to defaults, which means that everything will be permanently gone.
