Anyone have issue with the sub cutting out? I notice somewhat often that the light on the sub turns on and off. Is this a result of losing power, or connection to the soundbar? null

Question

ThinkDigital · Accepted Answer

I'm having this issue too. The subwoofer is sitting 2 feet directly before the soundbar with nothing in between and it fades in and out like waves. Like every 2 seconds. In then out then in then out, etc.

Thanks for letting me know I am not the only one with this frustration. I moved my wirless modem which was placed next to the subwoofer. Set up looks messy on my living room but it seems to have worked. Moved it about 3ft away. Hope this helps some one. I love my music loud. But yes...next time will not go wireless.

I had the same problem and can confirm that it is the Wi-Fi that is interfering with it. I had to Wi-Fi modem sitting right on top of this and when I moved the speaker away from the Wi-Fi it works flawlessly.

Hollywood · Answer

You need to turn the speaker’s port facing the sound bar! Literally the back of your speaker needs to point toward the modem! It works!

Woody · Answer

I had this same issue. Very very annoying. I had the sound bar for 3 weeks before my cable was set up. Sound bar work flawlessly. Got cable installed with Wi-Fi modem and then the sub would cut out every 45 secs or so over and over. Very frustrating. I moved the modem with little change. Then I moved the sub and I haven't had an issue since. The sound is great when everything is working. Don't give up on the system too soon! I found a solution and I am happy once again with my purchase. I would still by LG again.

Jeff · Answer

I turned the auto power function to off (long press "i" button) and it has worked flawlessly. I don't have an explanation as to why it worked but after so much frustration I don't really care!

BigBoyBev · Answer

Had the same issue but thanks to all of the reviews we read I moved the subwoofer to the other side of the room, away from the wireless router, and solid, good quality surround sound!

Erik · Answer

Have this issue ALL THE TIME.. as you described, every few seconds. I will never ever buy a bluetooth connected subwoofer / sound bar system again. When I bought this I was specifically looking for one with a cable connection but this severely limited my options. Very frustrating that they don't offer a hard-wire option for these products. As you described.. the Sub is directly below the sound bar.. separated only a IKEA cabinet which is mostly hollow with about 4mm of particle board on the edges. If the bluetooth signal cannot reliably get through that, then THIS PRODUCT SHOULD NOT BE USING BLUETOOTH. The designers of this product should have allowed for a TOSLINK or RCA hardwire backup option. Major oversight.

CFinDallas · Answer

I have a new LG Nano TV and purchased the LG Sk6Y soundbar and also use Appletv 4k Subwoofer constantly cutting in and out. I moved the subwoofer around and it really did not help. I upgraded firmware and zero help. TV also got the latest upgrade. Nothing helped. Here is what worked and my subwoofer doesn't cut in and out. I do believe it is a Bluetooth/Wi-Fi interference (which if you do a scan you will find a million Bluetooth sources and even neighbors WIFI)
1. I turned on the soundbar settings - enable Bluetooth Lock. This keeps the Bluetooth from "searching " for new Bluetooth sources and possibly getting interfered with.
2. I ran an ethernet cable from wi-fi router to my TV and another ethernet cable to my Apple 4k TV. 
I can still connect my iPhone to the AppleTV when needed to share but more importantly, it has been a month and I have had zero sub-woofer drops. I never wanted to hardwire with ethernet cables but my subwoofer works and actually does sound amazing so this is how it will stay. I will say that LG support was zero help.

Paulo · Answer

I tried everything and anything... everybodies comments made sense and they're all great ideas truly thought they would work still lost my mind over all of this cuz it's still kept cutting in and out and there was no way I was moving my subwoofer anywhere else except where I have it because I love the setup, then it dawned on me I recently got a new modem which is a dual band and I connected my TV to the 5G as soon as I connected to the 2.4 I've had no issues since go on your wireless settings and connect to the 2.4 instead that's what worked for me best of luck.

Answer

I was having the issue of the back speakers cutting in and out. After troubleshooting everything including relocating the modem I found the issue was actually the lg wireless tv interfering with the sound bar causing the back speakers to cut out. I then used a cable to connect the tv to the internet modem and it solved the problem. Hope this helps someone!

Rony · Answer

I had the same issue. It was very frustrating, until I changed the router channel to 6. All the problems went away. And I added rear speakers that made the sound so good. I wanted to throw the speaker out the window, now it's the best thing I bought.

McFly · Answer

Just found my cure to this issue. Check to see if your Xbox (PS4) is between your sound bar and subwoofer, as it’s connection to wifi may be interrupting the signal. To test this theory, I simply unplugged the Xbox and instantly the drop outs stopped. I ended up relocating the Xbox to completely solve the problem.

Answer

I was having this problem, and I think I fixed it when I moved my Alexa away from the top of the sub. Sort of the same thing as the wifi router issue.

Ellie · Answer

I have had this issue since i installed it and tried many different work arounds with no luck. I am so unhappy and frustrated as I paid good money for something (LG Model SP9YA) that I'd hoped would work well with my OLED LG TV. Instead I have to regularly turn off the sound bar and just use the TVs speakers because of the annoying in and out of the subwoofer. It is even more annoying when I have people over and they ask me "why does it sound like your sound is going in and out?" I totally regret not getting a wired system and agree with previous comments that there definitely should be a better blue tooth connection (sub is less than 2' away from sound bar) and they should absolutely give us the option to connect via wire. Very disenchanted and just wish the manufacturer would offer a better solution than thanks for the feedback for something that cost me a lot of money for results i could've paid far less for.

WolfieDog42 · Answer

From what I heard if your soundbar and subwoofer is close to your Wi-Fi router the Wi-Fi signal is so strong that it makes the subwoofer cut out The Wi-Fi signal interferes with the connection from your sound bar to subwoofer so my best bet of way to fixing this is to keep your Wi-Fi router out of the same room or at least a couple feet away from your sound bar or what you're using for a main connection to the subwoofer so it doesn't cut out

synthfox · Answer

Yes, I'm having the same exact issue. What an absolute garage product. Just give us the option of connecting the sub with a cable if wireless doesn't actually work!

Eric · Answer

Having an LG SN9YG where the sub woofer cutting out randomly. I turned the sub woofer to be able to see the light to be able to troubleshoot the problem. 

Than I noticed that the problem occured when someone using the laptop or the iPad.

With the inSSIDer software (WIFI analyzer) I saw that my 5G network was on the same channel than my subwoofer (channel 149).

I just changed the config in my router for the 5Ghz rather that have it in auto mode for the channel I selected a lower channel.

Problem solved

George · Answer

The review I read, solved the issue... I have my Modem moved away from the woofer, it works and it should stabilize the sound 
 Thanks

Jess · Answer

I have the same issue except myn is no where near the modem so it shouldnt be the cause of interference. It's very frustrating and makes me not want to ever buy lg again. My subwoofer stoped working for two days and now the sound just pulsates in and out. I reset the tv to default let it re update so the subwoofer would reconnect to the sound bar but like I said now it goes in an out not sure what's worse.

Adam · Answer

Same here. Sub is directly below the soundbar, still cuts in and out but less frequent than you guys say. Super annoying. I had a samsung product with wireless sub for like 10 years always worked amazing. In fact the samsung soundbar and sub are still working in my spare room.

Another poster said that make sure the back of the subwoofer was pointing towards the sound bar. I tried this and can confirm this worked.

Shawn · Answer

My new sub cut out every few minutes lasting a few seconds.  I read that moving the wireless Bluetooth sub across the room would help and voila it works like a charm. I am so pleased!

Greg · Answer

For anyone who is searching in late 2022. I figured out what was causing my issue.

I purchased a 65” OLED C2. Everything was fine for a couple week then I noticed my Samsung soundbar subwoofer and rear speakers were cutting in and out. I thought it was the soundbar  so I bought a brand new Vizio 5.1 and the problem still persisted. I tried moving the router and modem far away and still nothing.  With my tv on I switched the soundbar to Bluetooth and played music from my phone. the problem still happened. Only once I turned my LG tv off did it stop. While still hooked up to my phone I turned the tv back on, turned the Wi-Fi on the tv off, and it stopped! I then ran an Ethernet cable to my tv and the problem is completely fixed. The issue is with the LG tv’s wifi NOT the router.

I will be reaching out to lg to inform them of the issue.

Hope this helped!

Jonathanp · Answer

I just purchased a new 5.1 Vizio m series and had cutting out issues with the wireless subwoofer that’s behind my sectional . My tv is Ethernet my Xbox Ethernet wired. I was reading through these responses and I found the trick for me. My Wi-Fi booster that boosts Wi-Fi to my back bedroom soon as I unplugged it the cutting out disappeared.

MikMo · Answer

I have the SK10Y and the subwoofer cutting out has been a problem since day one. After trying practically all the remedies on this thread, nothing seemed to help. Then read one comment that said to change the channel on the 5g side of the wi fi router. Helps to have the wi fi analyzer to show which channels are open. Simply switch channels on the 5g side to one that's not occupied by any other device. Switched the channel about 4 hours ago and no drop outs since.

Answer

Thanks too all the tips, I found out moving my subwoofer away from the WiFi router is what worked for me!! Thank you thank you THANK YOU!!!!!

Steve · Answer

Read that the base speaker needs a line of site to the sound bar. Tried this, problem solved.

Rich · Answer

I had the same problem. I moved the sub as close as possible but it didn’t help. I moved the WiFi router to the other side of the TV, but still close to the soundbar, and it didn’t help. Finally I moved the WiFi router to an adjacent room and the problem went away completely.

DHunt · Answer

I simply moved mine to a different location, away from my wireless electronics. Problem solved. Sub is non directional sound, so place it anywhere within range.

Bobby · Answer

I had the same issue with an LG SK4D model soundbar. I had tried everything including changing my router settings to disable 2.4 ghz frequency to not interfere with the bluetooth. Nothing worked. Finally, I went to the LG website and downloaded a software update. It was fairly easy to install, all you need is a usb drive. Once installed, my connectivity issues were fixed. Hope this helps.

Mjpola · Answer

I moved my subwoofer away from the wifi router and it stopped fading in and out such a simple fix!!! Thank you!!! I would have never guessed this was the issue.

swankboy · Answer

I found this thread when I experienced the same issues with a new LG SN5Y soundbar. I noticed the bass would drop out frequently and it was very annoying; however, after reading a lot of these comments, and noting that most people solved their problem by moving the router/wireless modem/sub woofer due to interference, I changed the channel in my router, as it seemed like the easiest potential solution, and it worked. For my specific model, I changed the 5Ghz channel from default [153) to 165, and it works flawlessly. I love this soundbar so much since discovering the solution to the problem. Thanks to everyone who provided helpful and constructive comments. This may not work for everyone who ends up here, depending on your equipment you may have to change the 2.4Ghz channel instead, but I would suggest starting with the settings in your router or wireless modem. So much less of a pain than trying to relocate your equipment, wires, etc.

Dave · Answer

I read all the comments and did what seemed a logical answer which was wifi interference from a wifi router which was next to the soundbar behind the TV. I moved the router onto the floor and just like that, problem solved!!!

Eddie · Answer

My sub was doing all the same things everyone has been questioning about. I moved away from router, elevated it, 
Switch plugs and rooms with no effect. I took the 8 screw on the back and opened it up. Turns out power cable to circuit board was loose and pooped off as soon as I opened it up. Plugged back in, closed it up and works like it should. No problems since. BEFORE YOU DO THIS!! I don’t know it this voids warranty. Just throwing it out there. I wasn’t worried about that so I didn’t it anyway

Answer

I moved my wifi modem away from the sub and *POOF* no more cutting in and out!

Jake · Answer

I was having the same issue after I re located my wireless modem right next to it. All I did was relocate the wireless subwoofer away from the wireless internet modem. ( behind my sofa lol). It works perfectly now.

JoelF · Answer

Move the sound bar and/or woofer away from your router. You're welcome. :)

jcsandco · Answer

The source of the interference was my modem as was suggested in another post. It was too close to the sub. Once I separated them, I was up an running again without further issues

YESSSSS · Answer

Yeah. Definitely spent 8 months being annoyed by the in and out. Moved my sub four feet over. No issue.

James · Answer

Definitely the WIFI router interfering.

Barc · Answer

yes absolutely I can't figure out whats causing out or how to fix it

JRHUNTER10 · Answer

I had the same issue, tried turning auto adjust off and on, no change. Moved the Wi-Fi receiver to the other end of the entertainment center, about three feet, works perfectly now.

TheRevenite · Answer

I know this is an old topic, but I recently had this happen and fixed it rather quickly. Unplug both the subwoofer and the soundbar from power. Wait about 2 minutes and then hold the power button for 20 seconds. Plug the subwoofer and then the soundbar in. Power the soundbar up and your problem should be fixed. Being a proprietary wireless between the sub and bar, this process forces the bar to search for the sub and reestablish the connected. 

For complete sound cutting out when connected by Optical, make sure your TV is set for PCM and the Optical cable is not broken. If it's been bent (more than or equal to 90 degrees), the glass inside is most likely broken. You don't have to spend a fortune on a new one, the style that came with it is more than sufficient but brand names tend to have some form of warranty.


Hope this helps more people.

Jerma · Answer

Same thing was happening to me. I move the modem like 3 feet from the sub and it all good now. I hope that help who ever need tgis info.

Wakt · Answer

I too had this issue and after reading this thread I moved my sub to the other side of my media stand, away from my router, and it’s been fine ever since. Thanks all!

Answer

So I was also having an issue with the sub clipping/cutting out a few times every 4 or 5 minutes or so. After reading through here I saw all the things that people were doing and my sub and sounder actually Sith rich tin front of my router. I mean like the sub was almost touching the router and the bar was a good 2 feet above the router, I moved the subwoofer about 7 feet away and have not had any issues at all since. Not sure if this will fix everyone else's issues with their system but it worked for me. Good luck everyone.

Engnrgrad · Answer

I tried moving it to a different spot in the room, and it appears to work flawlessly now.

Justaguy · Answer

To solve the problem, I turned on something that always goes in and out in and out in and out then physically moved my wireless modem that's sits on top of my console, but under my sound bar, I moved it to the other end of the console, about 7ft, it stopped cutting out entirely, now it's 4 feet away from sub, three feet away from the soundbar...worked for me.

Raven · Answer

I bought mine from best buy in December 2018 as a gift for Christmas along with a 65" lg TV. My sound bar is now sitting 6" above the woofer and it cuts out all the time! So annoying. I have a 4year old Samsung sound bar system in my bedroom and the woofer is 15 feet away and it works just fine. I tried to return the sound bar to best buy but was told it was past their 15 day return policy. Stay clear of the LG sound bars this seems to be a common issue. LG tech support is useless as well. They said my wifi router and microwave are most likely too close even though they are on the other side of the house.

Answer

I did what this person suggested and it worked----I had the same problem and I fixed it quick what the help of an LG representative on a chat line and basically you have to reset the signal from the soundbar to the subwoofer unplugged you're soundbar then press the reset button on the back of your subwoofer and hold in for 10 sec release wait 30 sec.

I just turned the subwoofer to face backwards. 
It was previously over the router facing forward
. Works perfectly now.

Farnzo · Answer

I can also confirm that this could be an issue with the Wi-Fi router being too close to the sound bar. I upgraded to a much more powerful Wi-Fi router and immediately started having this problem really really bad. I moved the router about 20 feet away, and the sub almost works perfectly. However, on a rare occasion, the sub will still shut off for a second! I’ve considered sacrificing some range and switching my signal to 5g to see if the higher frequency interferes less. I just haven’t felt like going through the misery of reconfiguring everything on the network.

cjs3120 · Answer

Is your internet router causing interference. I had to raise my router above the soundbar and subwoofer I put it on a floating shelf at about the middle of my TV the modem is fine but if you have an all-in-one then even better. But the answer is router interference because for me it was when my wife would turn on Netflix in the other room the internet we kick on the beans would go through the soundbar and this is the sk9y you know a $900 LG soundbar so I was really mad and I tried switching back to the original router no I just got an idea to move it and I set it on top of my three tier glass TV stand and it works I'm going to just put a little higher to get better reception to

Jeff · Answer

I was having this same problem. I reset everything and it seems fixed now. Here's what I did... On the main soundbar, press and hold the wireless/bluetooth button on the back until the screen says "Reset". On the back of the subwoofer, press and hold the pairing button until the link starts flashing. When the light goes solid, that means it's reconnected. You might have to turn the main bar off and back on again in order to make the subwoofer pairing happen. On the back of the box to which the rear speakers connect, you'll need a paperclip in order to press the pairing button. When the light starts flashing, it's searching for the main soundbar. Just like the sub, it might help at this stage to turn the main bar off and on again. When the light goes solid, it's connected. And now that all three components have been reset and repaired, hopefully the intermittent cutting out will stop. It seems to have worked for me (so far?). Good luck.

IanKraZ · Answer

I just recently bought an LG sound bar. Just to note my modem is in the other room (shouldn't interfere) and my microwave is also in a completely different room, but my sound bar waves in and out. Not as bad as stated prior to mine, but still annoying. The subwoofer is 3 to 4 feet below the sound bar. The sound bar sits on my fireplace mantle. The subwoofer sits just to the fire place's side. It should work good, but no. Is it the bluetooth that is the problem? Because if so I would like to find a solution before I deside to return it.

I had this same problem for quite awhile. I even went out and bought a new LG sound bar after checking all the cables and connections and still had the issue. I figured it had to be the TV since all our TVs, sound bars and Blue Ray players are LG I knew it wasn't a compatibility issue.

In December I bought a LG Nano 8 TV and STILL had the issue. I decided to go for Mr. Google's help and within a minute had this fix. Less than a minute later my sub dropout problem was gone. LOL

Aaron · Answer

Ive been dealing with the subwoofer cutting in and out for 6 months now. I was going nuts over this whole thing, because I spent like $600 bucks on this thing. All it was, was the auto volume needed to be turned off. It will make it where you need to turn the volume up to a higher number, but it works perfectly now.

LilBob · Answer

Just turn the auto volume off

Adam · Answer

Had it happening as well. I live in an apartment and it would cut out every 5-10 seconds. My router was next to it but inside my tv stand. I simply moved the sub to the other side (farther side away from router) of the tv stand and it fixed the issue. Hope this helps!

It happens i have had this for 3 days and its mostly due to interference from other things in the household. I moved it closer to the bar and haven't had issues at all.

LG Digital Customer Care · Answer

Hi Larry. We regret to read that you are experiencing dropouts from the subwoofer of your LG - 2.1-Channel Soundbar System with Wireless Subwoofer and Digital Amplifier - Black, Model # SH3K. There are a few things you can do to troubleshoot the issue. Check that you do not have any products such as a microwave or other device nearby that is operating in the same frequency range as the Soundbar. This is a Class 2 Bluetooth device which receives and transmits RF electromagnetic fields in the frequency range of 2.4 to 2.4835 GHz. The closer the Subwoofer is to the main unit, the better the sound quality. YOu also want to make sure that they aren't any obstacles between the main unit and the subwoofer. Electrical conduits within the walls can als adversely affect the Bluetooth signal as can a router. If all these check out, then the unit might need to be inspected...^IFV

“Anyone have issue with the sub cutting out? I notice somewhat often that the light on the sub turns on and off. Is this a result of losing power, or connection to the soundbar?”
