Why Does My LG Sound Bar Subwoofer Keep Cutting Out?

Whether you’re listening to music or watching a movie, an LG soundbar is a great way to enhance your experience. That is until your soundbar subwoofer keeps cutting out for no reason. This problem is extremely annoying and inconvenient. If you want to get back to your listening experience, you’ll have to solve it in a timely manner.

Your LG soundbar subwoofer keeps cutting out because of Bluetooth interference, software problems, or outdated hardware. Each of these issues can cause your subwoofer or soundbar to cut in and out and make for a bad experience. Optic cable issues are also a possibility for a subwoofer that keeps cutting out. 

Subwoofer problems aren’t just unique to LG products. No matter what brand of soundbar subwoofer you have, you’re liable to run into the same problems of the sound cutting in and out. In this article, we’ll address each of the possible problems and look at what you can do to fix them.

Why Does My LG Subwoofer Keep Cutting Out?

Your LG subwoofer is mostly likely cutting out due to Bluetooth interference, outdated software, or old hardware in need of an upgrade. No matter what the cause is, the problem is always annoying and inconvenient. Most modern subwoofers are wirelessly connected to the devices that they are providing sound for. Because they’re wirelessly connected, they rely on a Bluetooth connection to operate.

While Bluetooth is the most common reason for your subwoofer cutting in and out, it’s not the only possibility. Let’s take a look at what the different problems might be.

Bluetooth Problems

Bluetooth connectivity allows for a wireless connection between your subwoofer and your TV. Bluetooth can be finicky, however, and the more devices you have operating with Bluetooth the more likely a problem is to occur. These days, anything from your phone to your Ipad to your TV can be connected to something via Bluetooth. If too many of them are connected at once, you’re more likely to have interference.

You Need a Software Update

Another common mishap for subwoofers or soundbars is that they are operating with outdated software. Every year, LG and other companies produce new technology with new software. At some point, if you’re using an older soundbar, your software will need to be updated to be compatible with your other technology.

Hardware Issues

If your soundbar has gotten damaged in some way and has a physical defect, the chances of cutting in and out are even higher. You might have dropped your bar or banged into it with something, or maybe even splashed it with water. There’s also a lot of internal wiring inside of your soundbar which might be nicked or frayed. Either way, hardware damage will definitely cause issues with cutting in and out.

Why is My Soundbar Cutting Out?

A soundbar that’s cutting in and out for no apparent reason is a nuisance. It’s distracting to you while you’re listening to music or another form of entertainment. While Bluetooth problems are the most common reason for cutting in and out, there’s another possibility. If your soundbar is operating without a rear satellite kit, but the signal source is configured for surround sound, the sound will be glitchy.

This is a fairly rare problem, however, and can be fixed with a simple software update. If your software is updated and your hardware is in good shape, you’re likely facing a Bluetooth issue.

My Subwoofer Keeps Disconnecting From Soundbar

Subwoofers are a great way to increase your viewing or listening experience. Unless it keeps cutting in and out, of course. There are different sets of problems based on the age and style of your subwoofer. Cutting in and out is rare with hardwired subwoofers, but it’s not unheard of.

Both your subwoofer and your TV have a lot of internal and external wiring when they’re hardwired together. It’s possible that one of the wires has gotten frayed or damaged and is experiencing temporary disconnections. Every time the wire disconnects, your sound will cut out. When it reconnects, the sound will cut back in. Wiring issues are difficult to fix properly and you would do well to invest in a subwoofer with Bluetooth connectivity.

DIY Tips for Subwoofer Disconnecting from Soundbar

Let’s look at a few possible fixes to each of the most common problems with a subwoofer cutting in and out.

For Bluetooth Problems

There are two possible solutions if you’re experiencing Bluetooth interference. The first option is to go through your house and disconnect all your devices from their respective Bluetooth connections. An area can only handle so many connections at a time and the system can get overloaded and cause interference.

The other option you have is to bypass Bluetooth altogether and hardwire your TV to your subwoofer. No matter how old or new your TV and subwoofer are, there should be a place to connect a wire between the two for improved sound quality. LG products, in particular, usually offer multiple options for a hardwired connection.

For Software Problems

The easiest and best solution for a software problem is to perform a software update on your subwoofer. Depending on the brand of your device you may have to contact the maker for exact instructions about performing a software update.

For Outdated Hardware

Depending on how old your subwoofer is, you might be better off replacing it once it’s damaged. Newer subwoofers have better overall quality and it’s expensive to repair speakers and subwoofers.

LG Soundbar Subwoofer Keeps Cutting Out Optical Cable

If your LG soundbar keeps cutting out and you’re using an optical cable, there’s a good chance that it isn’t tight enough. If your connection is tight and secure, there’s also a chance that the soundbar simply isn’t compatible with the TV.
