Many people buy an LG TV for its great picture and smart features. But sometimes, when you try to change the sound settings, you find some options are greyed out—that is, you can see them, but you cannot select or adjust them. This can be frustrating, especially if you want better sound for movies, games, or music. Why does this happen, and what can you do about it?
This article explains everything about LG TV sound settings greyed out. You will learn why this problem happens, which settings are affected, and how to fix or work around it. Whether you have a new LG OLED, a NanoCell, or an older model, the solutions below will help you get the sound experience you want. Along the way, you will find practical tips, real examples, and answers to questions most people don’t think to ask.
Why Are Lg Tv Sound Settings Greyed Out?
If you see sound options on your LG TV that are not selectable, you are not alone. This happens for a few common reasons. Understanding the cause is the first step to fixing it.
1. External Device Connections
When you connect devices to your LG TV, such as a soundbar, AV receiver, or headphones, the TV sometimes disables internal sound settings. For example, if you use an optical cable for audio output, many TVs will not let you change certain audio processing settings. The TV assumes the external device will handle those adjustments.
Example: If you plug in a soundbar using HDMI ARC, you may find settings like Balance or Equalizer greyed out. The TV is sending audio to the soundbar, so it no longer lets you adjust those settings.
2. Audio Output Mode
Your LG TV offers different audio output modes: TV speakers, Optical, HDMI ARC, Bluetooth, or sometimes even Headphones. Each mode supports different features. If your output is set to something other than TV Speakers, you will often see many sound options unavailable.
Example: If you use Bluetooth headphones, you may notice the Dolby Atmos or Surround Sound settings are not available.
3. Broadcast Or App Limitations
Some apps and broadcast signals control which sound settings you can use. For example, if you are watching Netflix in certain modes, you might not be able to adjust the Sound Mode or Audio Description. Some apps use their own audio processing, so the TV disables its own controls.
4. Content Format
Not all sound settings are available for all audio formats. For instance, if the source content is stereo, you cannot enable Surround or Dolby Atmos. The TV will gray out these options because the input signal does not support them.
Non-obvious insight: Many users don’t realize that when the TV receives audio through HDMI from a set-top box, the box’s audio format can also limit available TV sound settings.
5. Software Or Region Restrictions
Certain features are only available in specific regions or with the latest software. Outdated firmware may cause options to be greyed out. Also, LG sometimes removes or adds features through software updates based on country regulations.
Common Lg Tv Sound Settings That Are Greyed Out
Not all sound settings are affected the same way. Here are the most frequently greyed-out options on LG TVs, and why:
- Sound Mode: Controls presets like Standard, Cinema, Game, Clear Voice, and more.
- Greyed out when using external speakers or unsupported audio input.
- Equalizer (EQ): Lets you adjust bass, mid, and treble frequencies.
- Disabled when using HDMI ARC, Optical, Bluetooth, or external speakers.
- Balance: Adjusts volume between left and right speakers.
- Unavailable if TV speakers are not the output device.
- Dolby Atmos: Enables immersive audio.
- Not available unless the TV detects a compatible signal and device.
- AI Sound Pro: LG’s automatic sound enhancement.
- Sometimes locked when using non-TV speakers.
- Surround Sound: Simulates multi-channel sound.
- Only active with stereo or TV speakers.
- Audio Description: Provides narration for the visually impaired.
- Greyed out if the program or app does not support it.
- Digital Sound Out: Lets you choose between PCM, Auto, or Pass Through.
- Restricted in some app modes or when certain outputs are used.
- Volume Mode: Includes Auto Volume or Night Mode.
- Can be disabled based on app, region, or output.
- Bluetooth Audio Sync: Syncs audio when using Bluetooth.
- Only appears when Bluetooth device is connected.
How To Fix Greyed Out Sound Settings On Lg Tv
This section covers the most effective ways to unlock or access sound settings that are greyed out. Try these methods step by step.
1. Change Audio Output To Tv Speakers
The simplest fix is to use the TV’s built-in speakers. Go to Settings > All Settings > Sound > Sound Out and select TV Speaker. Most greyed-out settings will become available.
Tip: If you want to use a soundbar or receiver but adjust sound settings, temporarily switch to TV Speakers, make your adjustments, then switch back. However, settings like EQ may only affect TV speakers.
2. Disconnect External Devices
Unplug any optical cables, HDMI ARC, or Bluetooth devices. This forces the TV to use its own speakers and unlocks more settings.
Example: If you disconnect your HDMI soundbar, the Equalizer and Sound Mode options should be selectable again.
3. Use Compatible Audio Formats
Make sure the input device (game console, set-top box, Blu-ray player) is sending a compatible audio format. Set the source to output PCM or Stereo if possible. Some features like Surround and EQ only work with these formats.
Non-obvious insight: For some apps or HDMI sources, you may need to adjust the audio settings on the device itself—not just on the TV.
4. Update Tv Firmware
An outdated LG TV operating system can cause bugs or missing features. Go to Settings > All Settings > Support > Software Update and check for updates. Install the latest version and restart the TV.
5. Restart The Tv
Simple, but often effective. Power off your TV completely (not just standby) and unplug it for a minute. Plug it back in and restart.
6. Reset Sound Settings
If nothing else works, try a factory reset for sound settings. Go to Settings > All Settings > Sound > Sound Reset (or Reset to Initial Settings on older models). This clears any glitches that might block settings.
7. Check Regional Or App Restrictions
Some settings are not available in all countries or on all apps. If you are using a streaming app, try switching to live TV or another app to see if the settings unlock.
8. Use External Device Controls
If you must use a soundbar or receiver, remember that you should adjust sound using the external device’s remote or app. LG disables TV sound controls for external outputs, so use the soundbar’s settings instead.
Real-world Examples And Situations
Let’s look at some common scenarios where LG TV owners run into greyed-out sound settings, and what you can do in each case.
Scenario 1: Watching Netflix, Sound Mode Greyed Out
Many LG TV users notice that when they open Netflix, the Sound Mode option is not available. This happens because Netflix uses its own audio signal, and the TV’s processing is limited. Try switching to another app or input—if Sound Mode works, it’s an app limitation.
Solution: Use your soundbar’s settings if you need more control, or check if the Netflix app settings allow you to select a different audio track.
Scenario 2: Using Hdmi Arc Soundbar, Equalizer And Balance Greyed Out
When using HDMI ARC to connect a soundbar, the TV gives control to the soundbar for audio adjustments. The TV’s Equalizer and Balance are not available.
Solution: Adjust sound settings directly on your soundbar or receiver. Some high-end soundbars have their own EQ and sound modes.
Scenario 3: Bluetooth Headphones Connected, Dolby Atmos Disabled
If you connect Bluetooth headphones, the TV disables Dolby Atmos and Surround options. Bluetooth does not support these formats.
Solution: Use wired headphones for better compatibility, or switch back to TV speakers if you want surround effects.
Scenario 4: Tv Firmware Outdated, Missing Sound Features
Older LG TV models or outdated firmware may not support newer sound features like AI Sound Pro or eARC.
Solution: Update your TV’s firmware. If the hardware is too old, these features may not be available.
Scenario 5: Audio Output Set To Pcm, Pass Through Greyed Out
If you set your audio output to PCM, you may find that Pass Through or Auto options are greyed out.
Solution: Switch the source device to a compatible output format, or select a different TV audio output.

- Try a Different Input Source: Switch from HDMI1 to HDMI2, or from an app to live TV, to see if settings unlock.
- Factory Reset TV: As a last resort, reset the TV to factory settings. This will erase all custom settings.
Firmware And Region: Why Some Features Are Missing
LG often releases TVs with different features for different regions. For example, the same model sold in the US may have different audio options than in Europe or Asia.
- Firmware Updates: Some features are added or removed in updates. Always keep your TV’s firmware current.
- Regulations: Certain sound features may be disabled in specific countries due to laws or broadcasting standards.
- App Versions: Netflix or Disney+ may have different audio options in different regions.
Tip: You can check for updates on LG’s official website or through your TV’s menu. For more technical details, the LG Corporation Wikipedia page provides background on LG’s technology history.
How To Get The Best Sound From Your Lg Tv
Unlocking sound settings is not always possible, but you can still get great audio with these tips:
- Use a Quality Soundbar or Receiver: For movies and music, connect a good soundbar using HDMI ARC or eARC. Control sound settings on the soundbar.
- Optimize TV Speaker Settings: When using TV speakers, adjust EQ, balance, and sound modes for your room.
- Avoid Bluetooth for Movies: Bluetooth can introduce lag and reduce sound quality. Use wired connections for best results.
- Update Regularly: New firmware can improve sound features.
- Check App Settings: Some apps have their own sound options. Explore those menus for extra control.
Understanding The Limitations: What You Cannot Change
It is important to know that some sound settings are permanently greyed out in certain situations. For example:
- When using HDMI ARC, the TV cannot process sound modes—it just passes the signal.
- Bluetooth connections lack support for advanced audio formats.
- Some settings are only available for specific types of content (e.g., Dolby Atmos only with compatible movies).
Trying to force these settings can cause audio problems or sync issues.
Advanced Tweaks And Lesser-known Options
If you are comfortable with technology, LG TVs have a hidden Service Menu. Accessing it can sometimes unlock extra options, but it is risky. Changing settings here can void your warranty or break your TV.
- Access: Usually requires a special remote or code.
- Warning: Only for advanced users or technicians.
Another advanced tip: Some LG TVs allow you to set up audio profiles using the LG ThinQ app. This gives you more control, but only on supported models.
Data Table: App Compatibility With Lg Tv Sound Settings
Which streaming apps support which sound settings? Here is a quick overview:

|---|---|---|---|---|
| Netflix | No | Yes (with compatible content) | No | Yes |
| YouTube | Yes | No | Yes | No |
| Amazon Prime Video | No | Yes (with compatible content) | No | Yes |
| Live TV | Yes | No | Yes | Yes (if supported by broadcast) |
Is This A Problem With All Brands?
LG is not alone—Samsung, Sony, and other brands also restrict sound settings when using external devices. This is because TVs are designed to send audio to external audio systems without extra processing.
However, LG’s webOS menu design sometimes makes these restrictions more obvious, leading to more frustration for users.
Preventing Sound Settings From Being Greyed Out
To avoid this issue in the future:
- Plan your audio setup: Decide if you want to use TV speakers or an external system before changing settings.
- Read the manual: LG’s support site and user manuals explain which settings are available with each output.
- Check compatibility: Not all soundbars or receivers support all TV audio features.
- Update devices: Keep both your TV and external audio devices updated.
Frequently Asked Questions
Why Are Some Sound Settings Greyed Out When I Use A Soundbar?
When you connect a soundbar using HDMI ARC or Optical, the TV passes audio directly to the soundbar. This means the TV’s internal processing (like EQ or Sound Mode) is disabled. You should adjust sound settings using your soundbar’s remote or app.
Can I Unlock Greyed Out Sound Settings With A Firmware Update?
Sometimes. If your LG TV is running old software, new updates can fix bugs or add features. Go to Settings > All Settings > Support > Software Update to check for updates. But if a setting is greyed out by design (for example, when using external speakers), an update will not change this.
Why Do Apps Like Netflix Or Prime Video Limit Sound Settings?
Some apps use their own audio processing and do not allow TVs to change the sound mode or EQ. This is to ensure you hear the audio as the app intended, especially for formats like Dolby Atmos or surround sound.
Is It Possible To Use Both Tv Speakers And A Soundbar At The Same Time?
Most LG TVs do not support using both the TV speakers and an external soundbar at once. Some newer models allow “TV + Soundbar” mode, but this can cause audio sync issues. Check your TV’s sound settings for this option.
What Should I Do If All Sound Settings Are Greyed Out?
First, try switching the audio output to TV Speakers. If that does not work, disconnect external devices, restart the TV, and check for updates. As a last step, perform a factory reset or contact LG support for help.
Having sound settings greyed out on your LG TV can be confusing, but it usually has a clear reason. By understanding how your TV manages audio output and knowing which settings are affected, you can make the most of your TV’s sound features. Sometimes, the solution is as simple as changing the output mode or updating your firmware. Other times, you may need to use your soundbar or external device’s controls. With these tips, you can enjoy better audio and a smoother experience with your LG TV.
