LG OLED G2 Sound Cutting Out

If you're experiencing LG OLED G2 sound cutting out during movies, shows, or gaming sessions, you're not alone. This frustrating audio issue can stem from software glitches, HDMI handshake problems, or incorrect sound settings on your premium OLED television. The good news is that most sound dropout problems on the LG OLED G2 can be resolved with systematic troubleshooting—no technician visit required. Follow the steps below to restore consistent, uninterrupted audio to your viewing experience.

Quick Fixes for LG OLED G2 Audio Dropouts

Before diving into advanced troubleshooting, try these proven solutions that address the most common causes of LG OLED G2 sound cutting out. Work through each step in order, testing your audio after each one to identify what resolves the issue.

1
Power Cycle Your LG OLED G2: Unplug your TV from the wall outlet for at least 60 seconds, then plug it back in. This clears temporary cache files and refreshes the webOS operating system, which often eliminates minor software bugs causing audio interruptions. Press and hold the power button on the remote for 5 seconds after reconnecting power to ensure a full system restart.
2
Check HDMI Cable Connections: Loose or damaged HDMI cables are a leading cause of sound cutting out on the LG OLED G2. Disconnect and firmly reconnect all HDMI cables, ensuring they click into place. If possible, test with a certified Ultra High Speed HDMI 2.1 cable, especially for eARC connections to soundbars or receivers. Avoid cable lengths exceeding 6 feet for 4K/120Hz sources to prevent signal degradation.
3
Adjust Sound Output Settings: Navigate to Settings > Sound > Sound Out on your LG OLED G2. If using the internal speakers, select "TV Speaker." For external audio devices, verify that "HDMI (ARC)" or "eARC" is selected to match your physical connection. Mismatched output settings frequently cause LG OLED G2 sound cutting out as the TV struggles to maintain the wrong audio pathway.
4
Disable Auto Volume Leveling: Go to Settings > Sound > Additional Settings > Auto Volume and turn it OFF. This feature can create abrupt volume changes and perceived audio dropouts when content transitions between loud and quiet scenes. Also disable "AI Sound Pro" temporarily to test whether the built-in audio processing is interfering with specific content types.
5
Update webOS and Firmware: Press the Settings button, go to All Settings > Support > Software Update, and select "Check for Updates." LG regularly releases firmware patches that specifically address audio stability issues on the OLED G2. Install any available updates and allow the TV to restart completely before testing audio again.
6
Reset Audio Settings to Default: If sound continues cutting out, go to Settings > Sound > Additional Settings and select "Reset to Initial Settings." This restores all audio parameters to factory defaults without affecting picture calibration or app logins. After resetting, manually reconfigure only essential settings like your preferred sound output method.

Advanced Troubleshooting for Persistent Audio Issues

When basic steps don't stop the LG OLED G2 sound cutting out, deeper configuration changes may be necessary. These advanced techniques target HDMI-CEC conflicts, eARC timing problems, and codec compatibility issues that standard fixes miss.

First, try disabling SIMPLINK (LG's HDMI-CEC implementation) by going to Settings > General > SIMPLINK and turning it OFF. While convenient for universal remote control, SIMPLINK can cause handshake failures between devices that manifest as intermittent audio loss. Test with it disabled, then re-enable only if the issue resolves and you need the feature.

For eARC-connected soundbars or AV receivers, access Settings > Sound > Additional Settings > eARC Support and toggle it OFF, then back ON after 10 seconds. This forces a fresh HDMI handshake between your LG OLED G2 and audio equipment. Some users report success switching from eARC to standard ARC temporarily, then reverting after both devices stabilize.

If using Dolby Atmos content, verify your external audio device supports the specific Atmos format being delivered (Dolby Digital Plus vs. TrueHD). Incompatible codec passthrough causes brief but repeated audio dropouts. Set Digital Sound Out to "Pass Through" in Settings > Sound > Additional Settings for the most reliable external audio performance.

Important: Do not perform a full factory reset on your LG OLED G2 until you've exhausted all targeted audio troubleshooting steps. A factory reset erases all settings, app logins, and picture calibrations. Document your current picture settings with photos before resetting if absolutely necessary.

Frequently Asked Questions

Why does my LG OLED G2 sound cut out only when using Dolby Atmos content?

Dolby Atmos requires substantial bandwidth through HDMI eARC. Ensure you're using a certified Ultra High Speed HDMI cable, and verify your soundbar or receiver supports the Atmos format your source device outputs. Some older audio equipment cannot handle TrueHD Atmos from 4K Blu-ray players, causing dropouts. Switching Digital Sound Out from "Pass Through" to "Auto" in TV settings can force compatible transcoding.

Can a streaming app cause LG OLED G2 sound cutting out while internal apps work fine?

Yes. Individual apps like Netflix, Disney+, or Apple TV+ may have audio codec issues. Force-close the problematic app by holding the back button, clear its cache in Settings > Apps > [App Name] > Clear Cache, or uninstall and reinstall the app. Also check whether the issue occurs across multiple apps or is isolated to one specific service, which indicates an app-side rather than TV-side problem.

Should I contact LG warranty support for intermittent sound issues?

Attempt all software troubleshooting steps first, as most LG OLED G2 sound cutting out problems resolve without hardware service. If audio dropouts persist across all inputs and apps after firmware updates and factory reset, and especially if accompanied by visible symptoms like screen flickering, document your troubleshooting history and contact LG for warranty evaluation. The OLED G2 carries a 1-year parts and labor warranty with extended panel coverage for certain issues.
