LG S95TR No Sound: What Usually Causes It
If your LG S95TR has no sound, the problem is usually not the soundbar itself but the connection path between the TV, source device, and audio settings.
This guide walks through the most common causes and the fastest fixes so you can isolate the issue without guesswork.
The LG S95TR is a flagship Dolby Atmos soundbar system with HDMI eARC, wireless surround speakers, and support for modern TV audio formats, which means one small configuration mistake can mute the entire setup.
Start With the Fastest Checks
Before changing advanced settings, confirm the basics.
Many no-audio cases come from simple input or power issues.
- Make sure the soundbar is powered on and the display is active.
- Check whether the TV volume is muted or set very low.
- Confirm the soundbar is on the correct input, such as TV ARC/eARC or HDMI IN.
- Look for a muted source device, such as a streaming box, console, or Blu-ray player.
- Verify cables are fully inserted and not damaged.
If the soundbar display changes when you switch inputs, the unit is responding.
That helps narrow the issue to the signal path rather than the hardware.
Check the HDMI eARC Connection
The most common reason for LG S95TR no sound is an incorrect HDMI ARC or eARC setup.
For best results, connect the soundbar to the TV’s HDMI port labeled ARC or eARC using a high-speed HDMI cable.
Verify the correct port
On the TV, use the designated ARC/eARC HDMI port, not a standard HDMI input.
On the soundbar, use the HDMI OUT port that supports TV connection.
Enable eARC in TV settings
Many TVs require eARC to be enabled manually.
In the sound menu, set the digital audio output to HDMI eARC or ARC if available.
If the TV offers options like PCM, Auto, Pass Through, or Bitstream, start with Auto or Pass Through.
Test with ARC versus eARC
Some compatibility problems appear when eARC is active.
If there is still no sound, temporarily switch the TV from eARC to standard ARC and test again.
This can help identify handshake issues between the TV and the soundbar.
Adjust TV Audio Output Settings
Incorrect TV audio settings can prevent sound from reaching the LG S95TR even when the connection is correct.
Different TV brands use different menus, but the logic is the same.
- Set the TV audio output to external speaker, sound system, or HDMI ARC/eARC.
- Turn off internal TV speakers if your TV supports that option.
- Set digital audio output to Auto, Pass Through, or Bitstream for Atmos-capable sources.
- Try PCM if you only need basic stereo audio for testing.
If PCM restores sound, the source or TV may be sending a format the current settings do not pass correctly.
You can then refine the setting to support Dolby Digital, Dolby Digital Plus, or Dolby Atmos.
Confirm the Soundbar Input and Sound Mode
The LG S95TR can receive audio from multiple sources, so the input must match the device you are using.
If the soundbar is set to Bluetooth or another HDMI input, TV audio may not play.
Use the input selection on the remote or soundbar to switch back to TV ARC/eARC.
Also check whether a special sound mode or mute setting is affecting playback.
If the display shows a mute icon or volume indicator with no audio, raise the volume and disable mute.
Fix Wireless Subwoofer and Rear Speaker Problems
Sometimes users think they have LG S95TR no sound when only the subwoofer or rear channels are missing.
This often happens after power outages, router changes, or placement issues.
- Confirm the wireless subwoofer has power and a solid connection light.
- Make sure rear speakers are powered and paired.
- Move the subwoofer and rears away from thick walls, metal objects, and Wi-Fi routers if possible.
- Reboot the soundbar and unplug nearby wireless devices temporarily for testing.
If the front channels work but the surrounds do not, the issue is likely pairing or interference rather than a full audio failure.
Check Bluetooth, Optical, and Streaming Sources
If you are not using HDMI ARC/eARC, the fix depends on the source connection.
Bluetooth, optical, and app-based streaming each have different failure points.
Bluetooth audio is connected but silent?
Forget the soundbar from the phone, tablet, or laptop, then pair again.
Also verify the source device is not sending audio to another output such as headphones, a smart display, or another speaker.
Optical audio not working?
Use the TV’s digital audio out setting and ensure the optical cable is fully seated.
Optical does not support all immersive audio formats, so test with PCM or Dolby Digital first.
Streaming apps on the TV have no sound?
Check whether the app itself is muted or if the TV has different audio settings for internal apps versus external inputs.
App updates, HDMI handshake resets, and TV restarts often resolve this.
Power Cycle the Entire System
A full power reset clears handshake errors between the LG S95TR, TV, and source devices.
This is especially useful after firmware updates or input changes.
- Turn off the TV, soundbar, and source device.
- Unplug each device from power for at least 60 seconds.
- Reconnect the HDMI cable firmly.
- Plug everything back in and power on the TV first.
- Turn on the soundbar and then the source device.
This order helps the TV detect the soundbar correctly and renegotiate the audio connection.
Update Firmware on the TV and Soundbar
Firmware mismatches can cause audio dropouts or complete silence, especially with eARC and Dolby Atmos sources.
Keep both the LG S95TR and your TV updated.
- Check the LG app or LG support tools for soundbar firmware updates.
- Update the TV software from the manufacturer’s settings menu.
- Restart both devices after updating.
If your no sound issue started after a recent update, try resetting the audio connection by reselecting the HDMI ARC input and power cycling both devices.
Inspect Cable Quality and Compatibility
Not all HDMI cables are suitable for reliable ARC or eARC use.
A poor cable can cause random dropouts, one-way audio, or no sound at all.
Use a certified high-speed HDMI cable or Ultra High Speed HDMI cable, especially for 4K HDR and Dolby Atmos setups.
If you have another known-good HDMI cable, test it to rule out cable failure.
For optical connections, inspect the ends for dust or broken tips.
Reset the Soundbar if Nothing Else Works
If you have exhausted the common fixes, a factory reset can clear corrupted settings.
This is often the last step before contacting support.
After resetting, set up the LG S95TR again from scratch, reconnect the TV over HDMI eARC, and test with a simple source such as live TV or a built-in app.
Reconfigure advanced features only after basic audio works.
When to Suspect a TV, Source Device, or Hardware Fault
To isolate the problem, test the soundbar with another source device or another TV if possible.
If the LG S95TR works elsewhere, the original TV or source is the likely cause.
If no source produces sound, the soundbar may need service.
- Works with one device but not another: source settings or cable issue.
- Works on another TV: original TV ARC/eARC settings are likely wrong.
- No sound from any source after reset: possible hardware fault or service issue.
For owners of premium home theater systems, the key is methodical testing.
The LG S95TR no sound problem is usually solved by matching the correct HDMI port, enabling the right TV audio mode, and resetting the connection chain in the proper order.
