LG OLED B2 No Sound

If you're experiencing an LG OLED B2 no sound problem, you're not alone. Audio issues are among the most common complaints for this otherwise excellent OLED television. Whether your LG OLED B2 has no sound at all, intermittent audio cutouts, or sound only works through certain apps or inputs, this guide walks you through proven troubleshooting steps to restore your audio quickly. Most LG OLED B2 no sound issues can be resolved at home without professional service.

Quick Fixes to Try First

1
Check the Mute and Volume Settings: Press the Mute button on your LG Magic Remote to ensure the TV isn't muted. Press the Volume Up button repeatedly and watch for the on-screen volume indicator. If you see the volume bar moving but still hear nothing, the issue likely involves audio output settings or external connections rather than basic controls.
2
Test Different Content Sources: Switch between built-in apps (Netflix, YouTube), HDMI inputs, and over-the-air broadcast to isolate the problem. If sound works on some sources but not others, note which ones are affected. This helps determine whether the issue is global or specific to a particular input device or app.
3
Verify Audio Output Settings: Press the Settings button on your remote, navigate to Sound > Sound Out, and confirm the correct output is selected. If you're using the TV's internal speakers, choose "TV Speaker." If you recently connected a soundbar or receiver via HDMI ARC/eARC or optical, select the corresponding option. An incorrect setting here is a frequent cause of LG OLED B2 no sound complaints.

Advanced Troubleshooting Steps

4
Power Cycle Your TV Completely: Unplug the LG OLED B2 from the wall outlet for at least 60 seconds. While waiting, press and hold the TV's physical power button for 10 seconds to discharge residual power. Plug the TV back in and power it on. This full reset clears temporary software glitches that can cause audio failures.
5
Inspect HDMI and Audio Cables: Disconnect and firmly reconnect all HDMI cables, especially if using HDMI ARC/eARC for audio return. Try a different HDMI cable rated for HDMI 2.1 if available. For optical audio connections, check that the cable is fully seated and the small protective cap was removed. Damaged or loosely connected cables are common culprits behind sound problems.
6
Update WebOS and Reset Audio Settings: Go to Settings > Support > Software Update and install any available updates. LG frequently releases firmware fixes for audio bugs. After updating, navigate to Settings > Sound > Reset to Initial Settings to restore all audio parameters to factory defaults. Test sound again after both steps are complete.
Warning: Do not attempt to open the TV chassis or inspect internal speakers yourself. The LG OLED B2 contains sensitive electronic components and high-voltage areas that pose serious shock hazards. Internal hardware repairs require certified technicians with proper equipment.

When to Consider Hardware Replacement

If you've completed all steps above and still have LG OLED B2 no sound, the issue may involve failed internal components such as the main board, audio processing chip, or speaker assembly. Symptoms pointing to hardware failure include: burning smells from vents, visible physical damage to ports, sound that crackles before cutting out entirely, or audio failure that persists across all sources immediately from startup. In these cases, professional diagnosis is necessary.

Frequently Asked Questions

Why does my LG OLED B2 have no sound after a software update?

Post-update audio issues typically occur when sound output settings revert to defaults or become incompatible with your connected devices. Navigate to Settings > Sound > Sound Out and reselect your preferred output. If using HDMI ARC, toggle SIMPLINK off and back on. A full power cycle after updating also resolves most software-related audio conflicts.

Can a faulty soundbar cause my LG OLED B2 to have no sound through TV speakers?

Yes. When HDMI CEC (SIMPLINK) controls are active, a malfunctioning soundbar can commandeer audio output even when the TV speakers are selected. Disconnect all external audio devices, power cycle the TV, and test internal speakers alone. If sound returns, the issue lies with your external device or its CEC handshake, not the television.

Does the LG OLED B2 have a known audio defect I should be aware of?

Early production runs experienced intermittent eARC audio dropouts, particularly with certain AV receivers. LG addressed many instances through firmware updates. Ensure your TV runs the latest WebOS version. For persistent eARC issues, switching the HDMI port format from "Enhanced" to "Standard" in Settings > Channels > HDMI Settings sometimes stabilizes audio without sacrificing most content quality.
