LG OLED TV Sound Settings: Step-by-Step Guide

This guide walks you through changing the sound settings on an LG OLED TV, covering everything from basic volume adjustments to advanced audio modes, so you can get the best audio for movies, music, and gaming. You’ll need your LG OLED remote and access to the TV’s settings menu—no other tools are required.

What You’ll Need

  • LG OLED TV remote control
  • Your LG OLED TV (any recent model with webOS)
  • Optional: external sound system or soundbar (if you plan to configure audio output)

Step-by-Step

  1. Press the Settings button on your remote (the gear icon). This opens the quick settings menu on the right side of the screen.
  2. Navigate to “All Settings” at the bottom of the quick settings panel. This opens the full settings menu.
  3. Select “Sound” from the list on the left side of the screen. You’ll see all audio-related options here.
  4. Adjust the “Sound Mode” to match your content. The options typically include:
    • Standard – Balanced audio for everyday viewing.
    • Cinema – Enhances movie soundtracks and dialogue.
    • Sports – Emphasizes crowd noise and commentary.
    • Music – Optimizes audio for music playback.
    • Game – Reduces lag and enhances positional audio (if available).
    • AI Sound Pro – Automatically adjusts audio based on content (available on newer models).
  5. Set the “Sound Out” option to choose where audio is sent. Options include:
    • TV Speaker – Use the TV’s built-in speakers.
    • HDMI ARC – Send audio to a soundbar or AV receiver via the HDMI ARC/eARC port.
    • Optical – Output audio via the optical digital audio port.
    • Bluetooth – Connect wireless headphones or speakers.
    • WiSA – For compatible wireless speakers (on some models).
  6. If you’re using external speakers, enable “HDMI ARC” and ensure the external device is connected to the HDMI port labeled “ARC” or “eARC” on the TV. Then select “HDMI ARC” as the Sound Out.
  7. Adjust the “Additional Settings” for finer control. These include:
    • Balance – Adjust left/right speaker volume.
    • Equalizer – Manually adjust frequency levels (bass, treble, etc.).
    • AV Sync Adjustment – Fix audio lag if the sound is out of sync with the picture.
    • Digital Sound Out – Choose the audio format for optical/ARC output (e.g., PCM, Dolby Digital).
    • Auto Volume – Equalize volume between channels and inputs.
    • AI Sound Pro – Toggle the AI-enhanced audio processing.
  8. Use the “AI Sound Pro” feature if you want the TV to automatically optimize audio based on the content. This is great for general use, but you may want to turn it off for critical listening or gaming.
  9. Test your settings by playing content that represents what you usually watch. Adjust the equalizer or sound mode as needed until you’re satisfied.
  10. For advanced users, explore “Expert Settings” (if available) to tweak specific audio processing features like “Dolby Atmos” passthrough or “Sound Bar Mode.” These are typically found under the same Sound menu.

Common Mistakes

  • Forgetting to change Sound Out – If you connect a soundbar but leave Sound Out on “TV Speaker,” you’ll still hear audio from the TV. Always switch to the correct output.
  • Using the wrong Sound Mode – Leaving it on “Standard” can make movies sound flat. Try “Cinema” for films and “Game” for gaming.
  • Ignoring AV Sync – If audio is delayed, you might not notice it initially. Use the AV Sync Adjustment to fine-tune.
  • Not enabling HDMI ARC – Some soundbars require ARC to be enabled in the TV settings, not just the soundbar. Check both.
  • Over-boosting the equalizer – Cranking up bass can cause distortion. Adjust subtly.

Tips

  • Use AI Sound Pro for everyday viewing – It automatically adapts to content, saving you from constant adjustments.
  • For dialogue-heavy shows, select “Cinema” or “News” – These modes often enhance vocal clarity.
  • If you have a soundbar, set the TV’s “Digital Sound Out” to “Pass Through” – This lets the soundbar decode the audio format, often resulting in better quality.
  • Use the “Game” sound mode with a console – It reduces audio lag and emphasizes directional cues.
  • Calibrate the equalizer by ear – Play a familiar song and adjust frequencies until it sounds natural to you.
  • Update your TV’s firmware – LG occasionally improves audio processing with updates. Check for updates in the General settings.

Troubleshooting

  • No sound from the TV – Check that the volume is not muted and the volume level is above 0. Then verify the Sound Out setting is set to the correct output (e.g., TV Speaker if using built-in speakers).
  • Soundbar not producing sound – Ensure the HDMI cable is connected to the ARC/eARC port on both the TV and the soundbar. Set Sound Out to “HDMI ARC” and enable “SIMPLINK” (HDMI-CEC) in the General settings. Also, check that the soundbar’s input is set to ARC.
  • Audio out of sync – Go to Sound > Additional Settings > AV Sync Adjustment and adjust the delay until the audio matches the picture. For external devices, try changing the audio format to PCM.
  • Sound cuts out intermittently – This can be due to HDMI handshake issues. Try turning off the TV and external devices, unplugging them for 30 seconds, then plugging them back in. Also, check HDMI cable connections.
  • No audio via Bluetooth headphones – Make sure the headphones are in pairing mode and select them in the Sound Out menu. If they connect but no sound, go to Sound Out and ensure “Bluetooth” is selected.
  • Volume changes between channels – Enable “Auto Volume” under Additional Settings to equalize volume levels across different inputs and channels.

Frequently Asked Questions

Why is my LG OLED TV sound so low?

Check the volume level and ensure the TV is not muted. Also, check if “Auto Volume” is enabled, which can keep volume consistent. If using external speakers, verify the volume on those devices is turned up.

How do I connect a soundbar to my LG OLED TV?

Connect the soundbar to the HDMI ARC/eARC port on the TV using an HDMI cable. Then, on the TV, go to Sound > Sound Out and select “HDMI ARC.” Enable SIMPLINK in the General settings for better control.

What is the best sound setting for movies on LG OLED?

Select the “Cinema” sound mode. It enhances dialogue and creates a more immersive soundtrack. If your TV has “AI Sound Pro,” you can also try that, as it automatically adjusts to movie content.

Can I use Bluetooth headphones with my LG OLED TV?

Yes, go to Sound > Sound Out > Bluetooth, and pair your headphones. Note that Bluetooth audio may have slight latency, which can be noticeable in games or movies.

How do I fix audio lag on my LG OLED TV?

Go to Sound > Additional Settings > AV Sync Adjustment and adjust the delay. If the lag persists, try changing the Digital Sound Out format to PCM, which often reduces delay.

Does LG OLED support Dolby Atmos?

Many LG OLED models support Dolby Atmos, either through the built-in speakers or via HDMI ARC/eARC passthrough to an Atmos-compatible soundbar. To get Atmos, ensure your content and external device support it, and set Sound Out to HDMI ARC.
