Has your soundbar suddenly stopped producing sound? Work through these checks for power, mute, input selection, TV sound output, HDMI ARC or eARC, optical cables, Bluetooth and audio formats before replacing it.

A soundbar that suddenly produces no sound does not necessarily need to be replaced. The cause is often a muted device, the wrong input, an incorrect television sound-output setting, a loose cable or a failed HDMI ARC, eARC, optical or Bluetooth connection.

Work through the following checks in order. Begin with the soundbar’s power, volume and input before resetting equipment or arranging a repair.

Before you begin

Do not remove the soundbar’s cover or attempt to repair its internal power supply, amplifier or speaker components.

Disconnect the soundbar from power and arrange professional assistance if you notice:

A burning smell or unusual heat.
Smoke or visible scorching.
Crackling, popping or electrical noises.
Liquid damage.
A damaged power cable, plug or power adaptor.
Damage caused by impact or an electrical event.

If the soundbar uses a separate power adaptor, use only the adaptor supplied with it or a manufacturer-approved replacement with the correct specifications.

Confirm what has actually stopped working

Before changing any settings, determine which part of the system is silent.

The entire soundbar is silent: continue through the power, input, television-output and connection checks below.
The soundbar works but the wireless subwoofer is silent: the subwoofer may have lost power or its wireless connection to the soundbar.
The main soundbar works but the rear speakers are silent: the content, sound mode, speaker wiring or wireless rear-speaker connection may be responsible.
Only dialogue is difficult to hear: this is usually a sound-mix or centre-channel problem rather than a completely silent soundbar.
Only one application, channel or external device is silent: concentrate on that source before resetting the soundbar.

This article focuses primarily on a soundbar that produces no sound at all.

Check whether the soundbar has power

Look for a display, indicator light or other sign that the soundbar is turned on.

Press the soundbar’s physical power button.
Check that its power cable is firmly connected.
If it uses an external power adaptor, check the connection at both the adaptor and soundbar.
Make sure the wall outlet is turned on.
Test the outlet with another suitable appliance.
If the soundbar is connected through a power board, test it directly from a working wall outlet if safe and practical.

If the soundbar shows no lights, display or response from its physical buttons when connected to a confirmed working outlet, the problem may involve its power cable, adaptor or internal power supply.

Use the buttons on the soundbar

A flat remote battery, damaged remote or blocked remote-control sensor can make a working soundbar appear unresponsive.

Use the physical buttons on the soundbar to:

Turn it on.
Increase the volume.
Cancel mute.
Change the input or source.

If the physical controls work but the remote does not, replace the remote batteries and make sure nothing is blocking the soundbar’s remote-control sensor.

Check mute and volume on every device

There may be separate volume and mute controls on the television, soundbar, set-top box, streaming device and soundbar application.

Cancel mute on the television.
Cancel mute on the soundbar.
Increase the soundbar volume gradually.
If an external source has its own volume control, increase that volume as well.
Check whether a mobile application has reduced the soundbar’s volume.

Some soundbars display a mute symbol or flashing indicator rather than the word “Mute”. Check the model’s manual if the meaning of an indicator is unclear.

Do not raise the volume to maximum while troubleshooting. If sound suddenly returns, the result could be unexpectedly loud.

Select the correct soundbar input

A soundbar can remain powered on while listening to the wrong input.

Use its Source, Input or Function button to select the connection currently being used. The input may be labelled:

TV.
TV ARC.
eARC.
HDMI.
HDMI IN.
D.IN or Digital In.
OPT or Optical.
Bluetooth or BT.
Wi-Fi.
AUX or Analogue.

Do not assume that an input labelled HDMI IN is the television’s ARC input. Many soundbars have separate HDMI IN and HDMI OUT (TV ARC/eARC) connections.

If the correct input is selected, the soundbar may briefly display TV ARC, eARC, Optical, D.IN or the name of the connected Bluetooth device.

Test the television’s built-in speakers

Temporarily change the television’s sound output to its own speakers.

Depending on the television, look for:

Sound Output.
Speakers.
Audio Output.
TV Speaker.
Speaker Select.

Play the same program again.

If the television speakers work, the program and television are producing sound. Concentrate on the soundbar, its input, cable and audio-output settings.
If the television speakers are also silent, test another channel, application or external device.
If no television source has sound through either the television speakers or soundbar, restart the television and check its general sound settings.

Return the television to the external soundbar output after completing this test.

Check whether every source is affected

Test several different sources before resetting equipment.

Try another free-to-air television channel.
Open another built-in streaming application.
Play another program within the affected application.
Test a device connected to another HDMI input.
Open the television’s home screen and listen for menu sounds, if enabled.

If only one program or channel is silent, the source material or broadcaster may be responsible.

If only one application is affected, exit and reopen it, test another program, check for an application update and restart the television.

If only one external device is silent, restart that device and check its own audio-output settings.

Restart the television and soundbar

A temporary HDMI handshake, software or control problem can interrupt the sound connection.

Turn off the television.
Turn off the soundbar.
Turn off connected set-top boxes, streaming devices, game consoles or Blu-ray players.
Disconnect the affected equipment from power.
Wait approximately two minutes.
Reconnect and start the television.
Reconnect and start the soundbar.
Reconnect and start the source devices.
Select the correct television sound output and soundbar input.

Some televisions support a soft restart by holding the remote’s power button until the television restarts. Follow the instructions supplied for your model.

If the soundbar uses HDMI ARC or eARC

ARC stands for Audio Return Channel. It allows a compatible television to send sound back through a designated HDMI port to a soundbar or receiver.

eARC is an enhanced version that can support additional audio formats when both products and the connection are compatible.

For ARC or eARC to work, the HDMI cable must normally connect:

The television port labelled HDMI ARC or HDMI eARC/ARC.
The soundbar port labelled HDMI OUT (TV ARC/eARC), TV eARC/ARC or a similar description.

A standard HDMI input on the television may display video from a connected device but will not necessarily send television sound back to the soundbar.

Check the HDMI cable and ports

Turn off the television and soundbar.
Confirm that the cable is connected to the television’s ARC or eARC port.
Confirm that the other end is connected to the soundbar’s television ARC or eARC port.
Firmly reconnect the cable at both ends.
Check the plugs and cable for visible damage.
Restart both products.
Select the soundbar’s TV ARC, eARC, HDMI or D.IN input as directed by its manual.

If the soundbar has both HDMI IN and HDMI OUT ports, make sure the television is connected to the correct HDMI OUT port marked for TV ARC or eARC.

Test with a known-working HDMI cable if one is available. For eARC and high-bandwidth audio formats, use a cable that meets the requirements stated by the equipment manufacturer.

Select the soundbar in the television’s sound-output menu

Connecting an HDMI cable does not always change the television’s audio output automatically.

Open the television’s sound settings and select the appropriate external output, which may be labelled:

Receiver.
Audio System.
Soundbar.
HDMI Receiver.
HDMI ARC.
HDMI eARC.
External Speaker.

If the television immediately switches back to its internal speakers, check the ARC, eARC and HDMI-CEC settings and restart both products.

Check HDMI-CEC

HDMI-CEC allows compatible equipment to exchange control information. On many television and soundbar combinations, it must be enabled for ARC to work correctly.

Manufacturers use different names for HDMI-CEC, including:

Anynet+.
BRAVIA Sync.
Simplink.
VIERA Link.
Control for HDMI.
HDMI Control.
CEC.

Check the television and soundbar settings and enable the required HDMI-control feature on both products.

After changing HDMI-CEC, turn both devices off and restart them. Some equipment does not establish a new ARC connection until it has been restarted.

Check the eARC setting

If the television and soundbar both support eARC, set the television’s eARC mode to Auto or the setting recommended by the manufacturer.

If the soundbar supports ARC but not eARC, test the following:

Set the television’s eARC mode to Auto if it automatically supports ARC fallback.
Turn eARC off temporarily and test ordinary ARC.
Confirm that HDMI-CEC remains enabled.
Restart the television and soundbar after changing the setting.

Do not assume that enabling every advanced HDMI feature will improve compatibility. The correct setting depends on the capabilities of both products.

Test the digital-audio format

An unsupported or incorrectly negotiated audio format can result in silence from some programs while other content works normally.

The television may offer settings such as:

Auto.
PCM.
Pass Through.
Bitstream.
Dolby Digital.
Dolby Digital Plus.

Record the original setting, then select PCM as a diagnostic test.

If PCM restores sound, the previous surround format may not be supported across the complete connection.
If only certain Dolby Atmos or surround programs are silent, check the supported formats for the television, soundbar and connection method.
If Auto works but Pass Through does not, the television may need to decode or convert the audio before sending it to the soundbar.

PCM may reduce the available number of surround channels on some connections. Treat it as a troubleshooting test and confirm the final sound configuration afterwards.

If an external device connects through the soundbar

A game console, streaming device, set-top box or Blu-ray player may connect directly to the soundbar’s HDMI IN port, with video passed onwards to the television.

If that device is silent:

Select the matching HDMI input on the soundbar.
Confirm that the source device is producing sound.
Restart the source device.
Check its digital-audio format.
Firmly reconnect both HDMI cables.
Connect the source directly to the television for comparison.

If the source produces sound when connected directly to the television but not through the soundbar, check the soundbar’s HDMI input, supported formats and pass-through settings.

If the soundbar uses an optical cable

An optical cable carries digital audio from the television’s optical output to the soundbar’s optical input.

Check that the cable connects:

The television’s Digital Audio Out (Optical) port.
The soundbar’s Optical In, Digital In or TV Optical port.

Then:

Turn off the television and soundbar.
Remove any protective plastic caps from the cable ends.
Check that each plug is facing the correct way.
Push each plug in firmly without forcing it.
Check that the cable is not sharply bent, crushed or damaged.
Turn the equipment on.
Select Optical, OPT or D.IN on the soundbar.
Select Optical, Digital Audio Out or External Speaker on the television.

If there is still no sound, test PCM in the television’s digital-audio-output settings.

An optical connection does not normally allow every television to control the soundbar volume automatically. Use the soundbar remote while testing.

Do not connect optical audio to an input-only television socket

Check the labels carefully. The television must send sound from an optical output, while the soundbar must receive it through an optical input.

Some televisions use a combined or adaptor-based audio connection. Follow the television manufacturer’s instructions rather than forcing a standard optical plug into an unsuitable socket.

If the soundbar uses Bluetooth

A Bluetooth soundbar may appear in the television’s device list without being actively selected as the current sound output.

Try the following:

Set the soundbar to Bluetooth pairing mode.
Open the television’s Bluetooth speaker list.
Select the soundbar.
Choose Pair and Connect if requested.
Confirm that the television’s sound output changes to the Bluetooth soundbar.
Increase the volume gradually.

If it does not reconnect:

Remove or forget the soundbar from the television’s Bluetooth list.
Restart both devices.
Pair them again.
Move the soundbar closer to the television.
Temporarily disconnect nearby phones or tablets that may have connected to it automatically.
Check for television and soundbar software updates.

A soundbar may automatically reconnect to the last phone or tablet that used it. Disconnect that device before trying to pair the television.

Test the soundbar with a phone

If the soundbar supports Bluetooth, pairing a phone can help separate a soundbar fault from a television-connection problem.

If music from the phone plays normally, the soundbar’s amplifier and main speakers are operating. Concentrate on the television output, cable and connection settings.
If the soundbar pairs but remains silent with the phone and television, check its volume, mute and sound mode before resetting it.
If it cannot enter pairing mode or play sound from any supported source, a soundbar problem becomes more likely.

Disconnect the phone after testing so it does not keep taking control of the Bluetooth connection.

If the soundbar uses Wi-Fi

Some soundbars can receive television sound, music or control commands through Wi-Fi.

If a Wi-Fi connection has stopped working:

Confirm that the television and soundbar are connected to the intended network.
Restart the television, soundbar and router.
Check whether the soundbar appears in its manufacturer’s application.
Check for a soundbar firmware update.
Reconnect the soundbar to Wi-Fi using its application if necessary.
Test HDMI ARC, eARC or optical audio to determine whether the soundbar itself can still produce sound.

Do not reset the entire home network simply because one soundbar has lost its connection. First check whether other devices can still access the network.

If only one streaming application is silent

If the soundbar works with free-to-air television or other applications:

Exit and reopen the affected application.
Test another program.
Check whether the program uses a different audio format.
Select another audio track if one is available.
Restart the television or streaming device.
Check for application and device updates.
Test PCM temporarily.

If every other source has sound, avoid resetting the soundbar until the affected application or audio track has been ruled out.

If only one external device is silent

If a set-top box, console, computer or streaming device is the only silent source:

Restart the device.
Check its volume and mute settings.
Test another application or game.
Check its HDMI audio-output setting.
Test PCM or another compatible format.
Try another HDMI cable or television input.
Connect it directly to the television for comparison.

If other television sources play normally through the soundbar, the soundbar is unlikely to require replacement.

Disconnect additional equipment temporarily

HDMI switches, splitters, capture devices, converters and receivers can interrupt the audio path.

If practical, connect the television directly to the soundbar using a known-working HDMI or optical cable.

If sound returns, reconnect the additional equipment one item at a time until the interruption is identified.

If only the wireless subwoofer is silent

A wireless subwoofer normally requires its own power connection and a wireless link to the main soundbar.

Check the following:

The subwoofer is connected to a working power outlet.
Its power or link indicator is illuminated.
It is within the recommended distance from the soundbar.
It is not obstructed by large metal objects or enclosed inside a cabinet.
The soundbar is playing content that contains noticeable bass.
The subwoofer level has not been reduced completely.

Check the manual for the meaning of the subwoofer’s indicator colours and its model-specific pairing procedure.

Do not use another model’s pairing-button sequence unless the manufacturer confirms that it applies to your equipment.

If only the rear speakers are silent

Rear speakers do not necessarily produce constant sound. Their output depends on the program, audio format and selected sound mode.

Test with known multichannel content and check:

The rear-speaker receiver or wireless module has power.
Speaker wires are connected to the correct terminals.
The rear-speaker level has not been reduced completely.
The soundbar is receiving a compatible surround format.
A Standard, Surround or Adaptive mode is selected as appropriate.
The wireless module remains paired with the soundbar.

If the main soundbar produces sound, silent rear speakers do not normally mean that the entire soundbar must be replaced.

Temporarily turn off special sound features

Unusual sound modes or processing settings can sometimes cause confusion, particularly when changing between different audio formats.

Select a basic Standard sound mode and temporarily turn off features such as:

Night Mode.
Private listening.
Bluetooth headphones.
Wireless speaker groups.
AI Sound.
Adaptive Sound.
Virtual surround processing.
Voice-assistant output.

These features do not normally cause complete silence, but returning to a basic mode can simplify troubleshooting.

Check for software and firmware updates

Check every device involved in the sound path:

The television.
The soundbar.
The wireless subwoofer or rear-speaker system, if separately updateable.
The set-top box.
The streaming device.
The game console.
The affected application.

Keep each product connected to power while an update is being installed. Do not turn it off unless instructed by the manufacturer.

Restart the equipment and test several sources after updating.

Run the television’s built-in sound test

Many televisions include a sound test or audio self-diagnosis function under menus such as:

Support.
Device Care.
Self Diagnosis.
Sound Test.
Audio Test.

The test may play through the television’s internal speakers rather than the soundbar.

If the television test sound plays normally, the television can generate audio. Continue checking the external sound output and connection.
If the television’s own sound test is also silent or distorted, follow the television manufacturer’s troubleshooting instructions.

Reset the soundbar’s settings

If the soundbar powers on but remains silent from every supported source, a soundbar reset may restore incorrect input, network, HDMI-control or audio settings.

Reset procedures vary considerably between models. They may require:

A menu option.
A combination of physical buttons.
Holding a button for several seconds.
Using the manufacturer’s mobile application.

Use only the reset instructions for the soundbar’s exact model number.

A reset may remove:

Bluetooth pairings.
Wi-Fi details.
Subwoofer and rear-speaker pairing.
Sound-mode adjustments.
Room calibration.
Voice-assistant settings.
HDMI-control preferences.

Record important settings before resetting the soundbar.

Do not factory-reset the television too early

A complete television reset can remove application sign-ins, Wi-Fi settings, tuned channels, picture adjustments and connected-device settings.

Use a television factory reset only after:

Testing the television’s built-in speakers.
Testing several programs and sources.
Restarting the television and soundbar.
Checking the soundbar input.
Checking the television’s sound output.
Reconnecting the HDMI or optical cable.
Checking ARC, eARC and HDMI-CEC.
Testing PCM.
Installing available updates.
Following the manufacturer’s model-specific instructions.

Signs that the soundbar may require repair

A professional assessment becomes more appropriate when:

The soundbar shows no power when connected to a confirmed working outlet.
Its display or indicators repeatedly turn off unexpectedly.
It produces no sound from television, Bluetooth or any other supported source.
Its physical controls do not respond.
It repeatedly restarts or freezes.
Sound cuts in and out regardless of the source or cable.
Sound is accompanied by severe distortion, crackling or popping.
One section of the soundbar no longer produces sound.
There is abnormal heat, a burning smell or visible damage.
The problem remains after a model-specific reset.

A failed power supply, amplifier, control board, HDMI board, speaker driver or internal connection should only be inspected by a qualified technician.

When to contact the manufacturer or retailer

Contact the soundbar manufacturer, retailer or a qualified repairer when:

The soundbar cannot produce sound from any supported source.
It does not respond to its physical controls.
It cannot remain powered on.
The correct ARC or eARC connection repeatedly fails.
The soundbar will not complete a manufacturer-approved reset.
A supplied wireless subwoofer or rear-speaker module will not reconnect.
The product may still be covered by a manufacturer, retailer or extended warranty.

Do not pay for a repair or replace the soundbar before checking its purchase date and available warranty or Australian consumer-guarantee information.

What to tell the manufacturer or repairer

Before contacting support, record:

The soundbar’s brand and exact model number.
The television’s brand and model number.
Approximately when the problem began.
Whether the soundbar powers on normally.
Which input is selected.
Whether HDMI ARC, eARC, optical, Bluetooth or Wi-Fi is being used.
Whether the television’s built-in speakers work.
Whether the soundbar plays music from a phone.
Whether every application and external device is affected.
The selected digital-audio format.
Whether PCM was tested.
Whether HDMI-CEC and eARC were checked.
Whether another cable was tested.
Whether the television and soundbar were restarted and updated.
Whether a model-specific soundbar reset was completed.

Take photographs of the cable connections, input display and indicator lights. This can help support identify an incorrect port or interpret a warning indicator.

The bottom line

A silent soundbar is commonly caused by the wrong input, mute, an incorrect television sound output, a loose cable or an ARC, eARC, optical or Bluetooth connection problem.

First confirm that the soundbar has power, increase its volume gradually and select the correct input. Test the television’s built-in speakers, then restart both products.

For HDMI, confirm that both ends use ports marked ARC or eARC, select the soundbar in the television’s sound-output menu and enable the required HDMI-CEC setting. For optical audio, confirm that the cable is fully seated, select the optical input and test PCM.

If the soundbar plays music from a phone but not from the television, concentrate on the television output and connection rather than replacing the soundbar. If it remains silent from every supported source after a model-specific reset, contact the manufacturer or a qualified repairer.
