“Why is my Sony sound bar crackling?” Well, you are not alone in this, a couple more Sony sound bar users have had the annoying crackling/popping sound. And it is time you get rid of it following this article.

Your Sony sound bar is crackling due to cable not being firmly connected, fried woofer voice coil, or volume level set too high, which clips the amp. A damaged wire or wireless interference will also cause a Sony sound bar to crackle or pop.

Common cases showed this to be speaker sound interference, so you want your sound bar placed in a different corner. If the problem is not solved, try playin g from a different source.

What causes a Sony sound bar to crackle?

A Sony sound bar will crackle for many reasons. Consider looking into the possible causes below:

  1. The speaker cable connected to the sound bar and receiver is not firmly connected.
  2. The audio source is problematic, and you have not played a different source.
  3. The shielding of the Sony sound bar wire has a cut, causing an audio problem.
  4. One of the sound bar connections at the receiver could be the cause of the distortion, meaning you get rid of that one only.
  5. The sound bar could be making a crackling noise because the speaker balance is set to the middle setting.
  6. You set the volume level too high, which clips the amp, and is not more than your Sony sound bar can handle.
  7. There could be an object in your box interior pressing against the back of the sound bar woofer, which results in the popping or crackling sound.
  8. If your sound bar comes with a subwoofer, it could be the problem. The surround or voice coil will get partially separated if the subwoofer has a mechanical defect. A fried subwoofer voice coil produces a unique burned electronics odor.

Before you return your Sony sound bar for a replacement, consider removing the driver from its cabinet for visual inspection.

Check for loose wires or any possible problem on the back of the driver that presses against the cone.

Do not remove the driver from the cabinet if you have warranty coverage – you may lose it.

How to Fix Crackling Speakers

You have to troubleshoot this problem with the following steps:

  • Turn off your Sony sound bar and audio source, and disconnect them from the power outlet.
  • Check if the speaker wires are firmly connected to the sound bar and audio source such as your TV.
  • Turn off other nearby smart electronic devices to check for possible sound interference.
  • Separate the sound bar speaker wires from any electrical wires it tangles with.
  • If the crackling does not stop, connect your sound bar to a different audio source to confirm if it is an audio source problem.
  • Otherwise, reset your sound bar to the factory default settings.
  • You may have to replace the speaker wires. If the crackling noise is gone, the problem is with the speaker wires.

Before you return the sound bar to Sony or the local store, check the following:

Wireless range

You want to ensure that the subwoofer stays within the wireless range of your Sony soundbar if it uses Bluetooth or Wi-Fi technology (for a smart audio source such as your smartphone).

Depending on your Bluetooth version, for instance, the range is limited. Obstacles such as furniture, walls, etc., can obstruct connectivity.

In this case, move your subwoofer or your soundbar closer within playable range to stop crackling.

Inspect for wireless interference

When playing your sound bar wirelessly, there could be possible interference preventing your Sony sound bar from producing the premium sound you want to listen to.

Look out for other wireless devices in the room, such as your wireless printer, smart TV, cordless phone, router, etc.

To detect sound interference, unplug the wireless device or turn off the wireless module – Bluetooth, Wi-Fi, etc. If this works but you need the wireless device active, move it farther from your Sony soundbar.

If the smart device with wireless connectivity has a different wireless channel setting, try a new channel.

Switch to a wired connection

The problem could be a wireless connectivity thing. Switch to a wired connection. If your Sony sound bar subwoofer is wirelessly connected to your Sony sound bar, consider using cables to see if the sound crackles.

This is also important if you cannot reposition your wireless devices to prevent interference.

If the crackling, popping or static noise stops, it is definitely an interference problem. When using a cable, you need shielded cable to prevent interference from other electronic devices.

Multiple connections, especially wirelessly, can cause interference problems, which can lead to crackling noise. To keep your sound bar sound from distortions to sound better, cut off unnecessary connections.
