Does anyone else get a popping or crackle from the subwoofer? Just updated and now it is worse... it's random... really kind of annoying :( null

Question

Bolly · Accepted Answer

I have had this soundbar for under three weeks and I am getting the same problem. The subwoofer is making popping sounds and overall sound distortion. It is so bad that I disconnected it until I can get it checked out.

I had this problem for a couple months so I went out and bought another soundbar thinking mine was simply old and on its last leg (2 years old). Last weekend I decided to hook up my LG soundbar upstairs until the problem was unbearable. Strangely by moving the soundbar the problem has COMPLETELY VANISHED. The one factor that I've read that could be the culprit is that when it was downstairs, it was right next to my Cable/Wifi router. There must have been some kind of interference...but whatever the reason, I'm happy I didn't throw it away when I bought my new one!

I was also having this issue on the SB36. Sub crackling even at low output. Really didn't make sense. 

My solution:

While soundbar is on, Unplug sub

Go to soundbar, hold Bluetooth & Vol down simultaneously for 5 seconds. 

Series of lights flash on the sounbar until it powers down. 

While it's off, plug in sub. 

Power on Soundbar. All is well. Hope this helps :).

I was getting a popping noise that came from BOTH the sub and the speakers in my LG Soundbar (originally I thought it was just the sub but when I unplugged the subwoofer, the same random popping noise would come for the soundbar speakers. Since both components were exhibiting the problem, I knew that the speakers nor the sub were blown (highly unlikely that both would blow). What I discovered is that different people in the house were changing the volume differently. The system will pop when the volume on the speaker is turned way up (all the way up) using the volume control for the soundbar and the TV is turn way down so basically you're getting normal sound. I turned the LG soundbar volume down to about 1/4 of it's max output with its remote and then hid the remote so it doesn't get used (my TV is an LG so it drives the LG soundbar via the TV). 

No more popping.

I had the subwoofer popping. I followed the advice in this thread and moved the sub woofer away from the cable router and it stopped immediately.

Kambriel · Answer

I unplugged the subwoofer and changed the input several times. Then I plugged the subwoofer back in, and no more popping. I suspect that a lot of the problems people are having is due to a bad bluetooth pairing. Either there's interference from another device like a router (the cable company internet router makes the speakers go crazy if I stream movies over it, but it's fine if I stream from my cisco router even though they're both streaming on the 5 ghz band) or something's blocking the signal. 

If it's a first time install, check everything. Try the subwoofer real close to the bar, where interference has to be really strong to overcome the bluetooth signal. If it crackles or doesn't get sound from the subwoofer, try shutting off the bar and plugging in the subwoofer, try unplugging and plugging in the subwoofer with the soundbar on, etc. Look for a solid blue light on the back of the subwoofer; a flashing light means it isn't paired.

If you play with it long enough, you're bound to get a clear signal. Then, put the subwoofer farther and farther away WITHOUT MESSING WITH ANYTHING. (You may need a long extension cord temporarily, but this is just troubleshooting.) If it begins to crackle and pop as you set it farther away, then it's interference. Get into the settings of any wi-fi devices anywhere near the soundbar and/or the subwoofer, and see if it's at 5 ghz. The bluetooth signal of the Soundwafe is on that band. If you can change to 2.5 ghz, good. If you can't, then you may end up getting a wi-fi router that works at 5 ghz but doesn't interfere with the Soundwafe. Hope this helps...

I have the same problem. It is persistent and unbearable. I have moved the Sub all over the room, away from the wifi router, etc. No luck. It's basically useless to me. My conclusion is that the product is poorly insulated. It is not designed to work in the environment is designed to live in - i.e. an entertainment center/area. Even when moving it far away the pops are non-stop. My meter indicates there exists no seriously strong signal noise. Put simply, the product is not well made/insulated from even minimal signal interference. BUT THE WORST PART: THE PRODUCT IS NOT DESIGNED FOR HARDWIRED CONNECTIONS TO THE BAR. So it's worthless and unfixable.

Thanks for posting this question because I had the same problem, and thought that it may have been defective or something. But reading your post made me try a little harder.

I moved the subwoofer much closer to the sound bar (the woofer was across the room, now it's 3 feet away). This stopped the crackling. So, I think it was wireless interference.

I wish this wasn't my answer because now my wireless subwoofer might as well be wired, but it worked for me.

Yani · Answer

I have mine over 1 year now and the cracking and pooping noise is really bad. The sun is less then 3ft away from the sound bar itself and still the same problem so I disconnected the sub for now until I can fix it or get a new one. Of course it’s out of warranty. Don’t get me wrong before this happened it was great and I love it.

So I have an LG sound bar 320 watts with a wireless sub woofer. The main sound bar squealed at some frequencies while watching movies. So today I tightened all the screws on the bar and it stopped. Now the problem was the cracking and popping the sub woofer made, it was horrible. So I unscrewed all the screws and stuffed a few old towels into the cabinet of the speaker and put it back together. Now it has deep bass with no vibrations, cracking or popping....simple fix.

I know your comment was long ago but I do get that annoying noise!

DaPete · Answer

I had the same issues, and after research found this thread. My router and sub are about 10ft apart so I started working that solution. But first I restarted my router to see if it would find a better wifi channel and the issue resolved itself! I had my sound bar and sub up and running during the restart and I don't think the system would have been on when the router was set up. I (so far) haven't needed to move anything and the popping went away and the low-end response is much better!

The equipment - so I have the LG Soundbar, Sub and two rear speakers connected via Bluetooth. 

How it's hooked up - I have it from my computer to the sound bar with an optic cable. The sub is connected via Bluetooth about 3 feet away from the bar. The rear speakers have their own hub that they're wired to that's about 10ft from the bar. 

It worked great for about a day. Then I started getting a very noticeable static sound from the two rear speakers. I couldn't hear it from the bar or the sub and when I unplugged the hub for them it stopped. I reset it. Reset the bar. Checked for Bluetooth interference. And then started googling. The most likely scenario I could find was that it was too far from bar or a blown speaker. Both annoying problems as I just bought it and barely used it. 

Fun fact. Neither issue is right. I played around with my settings and things. As it's connected to my computer I have like 8 ways to control sound volume. Theres the sound on my computer, the sound the app or game has, even on the webpage itself you can control sound. Plus the actual sound on the soundbar.

So with all the options and for the most part sitting at my computer I decided to max out the volume on the soundbar and control it with my keyboard via the computers main sound. 

When I changed this around and went high on my computer and low volume on the soundbar (and whole system) the static went away. 

If you have it connected to a computer or a system with multiple ways of controlling the volume. Raise all the volume and use the bar itself to change the volume level. This is what fixed it for me. I'm not sure why, but it's like the sound when you turn a speaker way way up and have no sound come out but can still hear the speaker. It was like there wasn't enough input from my computer's sound to the bar to cover for how loud the bar was trying to be. .. if that makes sense.

We have had ours for about a month and is working fine. Could be a weak wireless single. Test by temporarily moving the speaker close to your wireless router. Additionally has seen a poor ground on the power outlet to the sub-woofer cause interference and lastly possibly a defective speaker. Generally I would lean towards the first two. Try to move the speaker closer to the WiFi router or to another power outlet see if it changes (suggest different room just as a test).

Had same popping sound from my vision subwoofer , I tried a few of the things that I read here, what ended up working for me was moving the subwoofer away from my wifi router and modem. Without a doubt it was interfering with the Bluetooth signal from my sound bar. We are now good as new ;) … hopefully this helps someone.

Raytown956 · Answer

I had the same problem and tried everything I read with no luck, but found what was wrong with mine. It was the speaker in the subwoofer. The magnet on the speaker was pried up one one side so that cause the inside coil was scraping against a magnet wall. I could not compress it down so I put a gap on the other side of the magnetic Using a big flat head screwdriver and a hammer. The subwoofer is working great now.

Yes just purchased a new Bravia and having intermittent crackling static noise from the speaker system. I checked the connection without any improvement.
Can you help?

Gnome · Answer

make sure if you have HD tv that your Dolby sound is off at the tv and the cracking noise will go away in the sound bar.

Ttouch · Answer

Unplug it and re pair it although it usually does it automatically. It happens every once in awhile. Not often I think it has something to do with the Bluetooth connection. Some people say moving it closer to the soundbar helps but not too close to a router. Trial and error is my best advice. Just know its not broken. Good luck. I absolutely love this btw!

Interference through cable. Move cable, wrap in aluminum foil, or buy nicer cord.

Soundaddict · Answer

Guys, unless it's a physical problem with the subwoofer, the solution is to connect the subwoofer to a different outlet.

Using the same outlet creates an interference that affects the connection.
