How to Fix Soundbar Noises (Crackling, Popping, Buzz, High Pitched)

Why is my soundbar making a crackling noise?

The reason why soundbars make crackling noises is because of a poor connection, interference from other devices, or broken down solders inside the soundbar.


Poor Connection

 It is the most common cause of the soundbar’s crackling noise. Your amplifier and speaker driver are connected via multiple wires. If any wire is making the driver move abruptly, it can lead to a poor connection and crackling noise.


Multiple Connection Problem

 The interference caused by the connection problem isn’t always easy to address. Sometimes, a bad connection occurs with multiple wires or parts of the device. While connection problem from a single wire is easier to find, others are really difficult.


Problems Inside the Soundbar

 Another common problem causing a crackling noise of the soundbar is poor connection inside the device. Due to regular wear and tear, solders can break down and need repair. Once you identify the problem, the fix is as easy as reconnecting cables.


How do I get my sound bar to stop crackling?

You can try to get your soundbar to stop crackling by checking for poor connection and inspecting for internal problems.


Check for Poor Connection

The first thing that you need to do is check for loose wires by turning OFF the device. You need to check the wires of both your speakers and soundbar. To ensure a secured connection, remove all the wires and reconnect them to the right ports.


Inspect for Internal Problems

 If the above method doesn’t work, you may need to uninstall your soundbar and speakers. You need screwdrivers and other tools that are recommended on the user manual to open your soundbar. Thoroughly check its internal parts and see if any solder is burnt or has broken down.

Why is my soundbar making a buzzing noise?

Humming or buzzing noise from soundbars can give you a terrible listening experience. Here are the most common reasons for your soundbar making a buzzing noise:

  • Connection problem
  • Damaged cords

Connection Problem

There are multiple wires and ports in your soundbar that should be properly connected to deliver an uninterrupted experience. If any wire is loosely connected to your soundbar, it can create a buzzing or humming sound.


Damaged Cords

Sometimes, the old cords get frayed due to long usage. If any cord of your soundbar is mildly damaged, it will deliver sound but will create a constant buzzing sound.


Problem in Other Devices

 If your soundbar is connected to your TV, maybe your soundbar is not the device that’s creating the buzzing sound. It could be a sound problem in your TV that’s leading to the buzzing noise.


The Content

Why is my soundbar making a popping noise?

The popping noise of your soundbar can occur due to multiple reasons. Here are the most common reasons that you need to look for:

  • Loose connection
  • Internal issues


Loose Connection

If a wire connecting your soundbar is loosely set, it can lead to a popping noise as you play any sound.


Internal Issues

 If your soundbar’s internal part is damaged or some components are loose, it can create a constant popping noise.

Why is my soundbar making a high pitched noise?

High-pitched sounds are really disturbing and they can ruin your listening experience. Here are the most probable reasons leading to high pitched noise:

  • Ground loop
  • Incorrect setup
  • Poor connection
  • Reverberation


  • Ground Loop: It is one of the most common causes of high-pitched noises. The ground loop can occur due to any electrical component of your soundbar.
  • Incorrect Setup: Soundbars are set with functions such as base and high pitch sound. If your soundbar is poorly set up, it can cause constant high-pitched noise.
  • Poor Connection: It is another common cause leading to high-pitched sound. If any wire of your soundbar is loose, it can be the source of this problem.
  • Reverberation: When you are playing audio on your soundbar, the subwoofer’s low frequency can create a huge reverb in the other objects in your room. Though the shaking won’t be noticeable, the high pitch sound will be quite disturbing.

How do I stop the high pitched noise coming from my sound bar?

To stop the high pitched noise coming from your soundbar, you need to solve ground loop, factor reset, reconnect all cables and stop reverberation.

  • Solve Ground Loop
  • Factory Reset
  • Reconnect All Cables
  • Stop Reverberation


  • Solve Ground Loop: To begin with, you need to disconnect all the cables and then connect them back. If the high-pitched sound is still there and you are able to identify the cable leading to this problem, you can consider using a coaxial isolation transformer on that cable.
  • Factory Reset: If the cause of the high-pitched noise is an incorrect setup, you need to go for a factory reset, which is pretty easy. You can follow your user manual’s instructions to completely reset your soundbar and solve this issue.
  • Reconnect All Cables: If the problem is occurring due to a loose connection, you are lucky because the hack is very easy. All you need to do is turn your soundbar OFF and then take out all the cords carefully. The next step is reconnecting all of them and seeing whether the high-pitched sound has gone.
  • Stop Reverberation: To try this method, you need to remove everything that is balanced on the subwoofers. No objects should be placed on the top of your subwoofers because that creates reverberation. If the high-pitched noise is still there, you can move the subwoofers to another area.
