Samsung Subwoofer Blue Light Is On, But No Sound.

The blue light in that device is the indication of turning on the speaker

The blue light in that device is the indication of turning on the speaker.

If this light is on, then you should see that your speaker is working, but maybe the issue is another that the speaker is not working. Some issues are the representation of the problem:

1- The Volume Is Set Too Low. 

If the volume on your Subwoofer is set too low, you will not be able to hear any sound coming from the speaker.

To increase the volume, press the volume up button on the Subwoofer or remote control. If you are using a Samsung soundbar, you can also adjust the volume using the soundbar’s remote control.

2- The Mute Function Is Enabled. 

If the mute function is enabled on your Subwoofer, you will not be able to hear any sound coming from the speaker. To disable the mute, press the mute button on the Subwoofer or remote control.

If you are using a Samsung soundbar, you can also adjust the mute setting using the soundbar’s remote control.

3- The Wrong Input Source Is Selected. 

If you are not hearing any sound coming from your Subwoofer, make sure that you have selected the correct input source.

For example, if you are trying to play music from your phone, make sure that the phone is connected to the Subwoofer via Bluetooth or an Auxiliary cable.

You can typically select the input source by pressing a button on the Subwoofer or remote control.

4- There Is An Issue With The Audio Cable. 

If you are connecting your Subwoofer to another device using an audio cable (such as an Auxiliary or RCA cable), make sure that the cable is firmly plugged into both devices.

If you are using an optical cable, make sure that the cable is inserted all the way into both devices and that there are no bent pins in either connector.

5- There Is An Issue With Bluetooth Pairing. 

If you are trying to connect your Subwoofer to another device via Bluetooth and you are having trouble getting them to pair, there are a few things you can try:

Make sure that both devices are within range of each other (typically 30 feet or less). If one of your devices has an NFC chip, try holding it close to the other device during Bluetooth pairing.

Delete any existing pairs between these two devices and try reconnecting them from scratch.

6- There May Be An Issue With Your Device’s Audio Output. 

If you are connecting your Samsung subwoofer to another device (such as a TV) and you are not hearing any sound coming from the speaker, there may be an issue with your device’s audio output.

To test this, try connecting another set of speakers or headphones to your device and see if you can hear sound coming from them.

If you cannot hear sound coming from another set of speakers or headphones, there may be an issue with your device’s audio output, and you should contact customer support for assistance.

7- There May Be An Issue With Your Subwoofer. 

If none of the above solutions solve your problem, there can be an issue with your Subwoofer itself.

In this case, we recommend contacting Samsung customer support for assistance.

USB stop working if you are using USB instead of the phone because you may not make the connection of the mobile good with the speaker because you can go urgently to work and also carry a phone with you, and this connection may not remain good.

You use USB as this does not need the connection. It works only when you attach this to the speakers.

The light of the speaker is on, but it has no sound; this means that the USB stopped working, which means it is not playing the sound more.

If it plays no more sound, then the issue is with the music or also with the USB. Here the issue is not with the speaker.

Check the music or USB as these are the cause of the problems. Otherwise, there is no problem, and your speakers are safe and not having problems in them.

8- Loose Wiring

Maybe the loose wiring is the issue; if something is facing an issue, you have to check the issue that how much the issue is and also how much it contains to be.

In this problem, the issue is with the wiring; maybe the wiring gets loose. Loose wiring is the thing that the speaker is still working on, but the main board of the speaker has an issue with the release of sound.

The sound is not coming, but the light is maybe on and still representing that the speaker is on, but the sound is still creating issues.

Check the issue that is in the wiring and, if possible so make it right by paying some attention and also by performance.

9- Mobile Disconnected

The speaker is connected, but the mobile is disconnected.

The speaker is on, but if the mobile gets disconnected as you go out from the zone of the connection, this is the cause of the loss in the signals.

When signals get lost, the problem is that when signals are not caught by the device, this does not display the sound.

Make sure that the device you are using for the connection can be kept in the zone of the connection.

When you get out of that zone, you can come to know that the speaker is on as the light of the speaker is on, but the speaker is not working, which means it does not give the sound, which is the main problem that you are facing and needs the solution.

Fix Samsung Subwoofer Blue Light On But No Sound

Using the correct port is important for the Subwoofer

1-  Check The Power Cord

First, check to make sure that the power cord is properly plugged into both the Subwoofer and the outlet.

If it is not, plug it in and try again.

2-  Check The Audio Input.

Next, check to make sure that the audio input is properly plugged into both the Subwoofer and the audio source.

The most common audio sources are a TV, Blu-ray player, or stereo receiver. If it is not, plug it in and try again.

3-  Adjust The Volume

If the power cord and audio input are both properly plugged in, then adjust the volume on the Subwoofer itself until you can hear sound coming from it.

4- Adjust The Eq Settings.

If you still cannot hear sound coming from the Subwoofer, then try adjusting the EQ settings.

These settings allow you to customize the sound of your Subwoofer to better match your specific preferences.

5- Check For Firmware Updates.

If you have checked all of the above and still cannot get your Subwoofer to produce sound, then there may be a problem with the firmware.

Firmware is software that is stored on a device that allows it to perform certain functions. In this case, you will need to check for any updates that may be available for your particular model of Subwoofer.

6- Ensuring The Use Of The Correct Port

Using the correct port is important for the Subwoofer to work properly.

Usually, the ports ( that are located at the back panel of the TV or any other device that you might want to use) are color-coded to make it easier to understand which cable should go into which port.

7- Checking Other Media Files

If you have noticed that increasing the volume of changing the ports has not worked for you, maybe the media is the issue instead of the Samsung Subwoofer.

To confirm this, play a media file that you have played earlier and are sure that it contains audio.

You can also play any well-rated and popular video from online apps like YouTube to confirm the same.

A loss of sound confirms that the Subwoofer, indeed, is damaged, while the audio sound indicates that the previous media file was corrupted.

Checking For Firmware Updates

Firmware updates are an important part of every device. They help in fixing various bugs and issues present in the system of the Samsung Subwoofer.

If you are facing the issue of no sound, try updating the firmware to make sure that the bug has been fixed in the latest update.
Here is how you can do it:

1) Press the Gear icon on the remote. This is the sound control button.

2) Press and hold the same button for 20- 30 seconds.

Note down the text appearing after the letter ‘B.’ This indicates the current firmware version.

3) Open the SmartThings app on your phone and update the device through it.

Resetting The Subwoofer

Resetting the Subwoofer is not what it seems.

You do not have to go through a plethora of buttons and menus to reset your Samsung Subwoofer and avoid Samsung Subwoofer blue light on but with no sound issue.

Simply unplug the Subwoofer from the power outlet for some time and then plug it back in.

This should reset it and erase the temporary glitches that were preventing the sounds from coming.

Play any media file to confirm that the sound is audible.

Other Possible Problems :

Samsung Subwoofer Not Connecting to the Soundbar

If your Subwoofer is not connected to your soundbar, you will need to reconnect it in order for it to work properly.

This should not come as a surprise to you. Although auto-connect is an option, most of the time, it won’t be successful.

It is highly recommended that you manually connect your soundbar to your Subwoofer.

Before you can correctly connect your soundbar, you must first connect the power cords for both your Samsung soundbar and your Subwoofer and then plug them in.

There is a little hole on the rear of the Subwoofer that is labeled ‘ID Set.’ You can access this hole by pressing the button on the Subwoofer.

A paperclip should be used to press the button found inside. Keep holding the button until you observe that the “Standby” light has gone out and the “Link” light has started flashing.

When the soundbar is still turned off, grab the remote, navigate to the ‘Mute’ button, and push and hold it.

Keep your finger pressed firmly on the button for a few seconds until the ‘ID Set’ message appears on your soundbar.

Turn on your soundbar as soon as you notice the blue LED light on the Subwoofer beginning to blink. If the blue LED light stops blinking once it has been properly attached, you will know that it is connected correctly.

It is possible that you will need to repeat this step in order to guarantee that the components are linked together in the correct manner.

If you are still unable to connect, verify that the firmware on your device is up to date and, if necessary, update the most recent version of the program.

Samsung Soundbar Subwoofer Quiet/Not Loud

Samsung subwoofer being too quiet

It is possible that you will experience a problem with your Samsung subwoofer being too quiet.

You could also run into situations in which the volume of your Subwoofer will swing from being at the appropriate level to all of a sudden being too low without you making any adjustments to it.

If you discover that the volume on your Samsung subwoofer suddenly drops or the volume is too quiet, the problem may lie with the firmware.

Verify that you are using the most recent version installed, and then carry out a sound check. You could want to check the audio settings on your TV because that might be the source of the issue.

After that, you will need to do a reset on both your soundbar and your Subwoofer. In the event that the issue continues to be a problem, the simplest remedy for you to do is to manually reconnect your Subwoofer to your soundbar.

Samsung Subwoofer Keeps Disconnecting From the Soundbar

There are some potential problems that could be the reason why your Samsung subwoofer keeps disconnecting if this is occurring.

You need to ensure that your soundbar and Subwoofer are correctly connected, that there are no obstacles in the way, and that there is no interference.

What steps should you take if your soundbar’s Subwoofer keeps detaching from it? It is recommended that you begin by turning off and then restarting both the soundbar and the Subwoofer.

Before reconnecting them to the power source, you should first unplug them for at least ten seconds. After that, reactivate both the Subwoofer and the soundbar simultaneously.

If an issue is not resolved by this, you should try doing a sound check. To muffle the sound, turn off your Subwoofer and then press and hold the “Mute” button on the remote for your soundbar.

Keep your finger on the button for a minimum of ten seconds. After you have completed those steps, you should then reset your soundbar and make an effort to manage the sound.

Inspect the area around your soundbar and Subwoofer to be sure there is no interference from either electronic or physical sources.

Even something as innocuous as placing a WiFi box in close proximity to your speaker can cause the signal to become garbled.

It should be located in a location that is separate from your WiFi modem.

If your Samsung subwoofer is still detaching from your soundbar, it is important to manually reconnect your Subwoofer to your soundbar so that you can continue using them together.

Samsung Soundbar Subwoofer Cutting Out

There is a possibility that you will face an issue in which your Samsung subwoofer is successfully connecting to your Subwoofer, but the sound quality is inconsistent.

This can be due to the requirement for an update to the system’s firmware, as well as checking the connections and restarting the machine.

If your Samsung subwoofer keeps cutting out, the following are some things you can do.

First things first, make sure that all of the connections to the soundbar and the subwoofers are functioning properly and that all of the connections are right.

In addition to this, you need to ensure that the source of the sound you are seeking to obtain is compatible with both devices.

It’s also possible that there’s a problem with the Subwoofer. You may demonstrate this by playing the audio again and checking it.
