LG web os TV and LG soundbar - sound drop/ Cutoff / issue wireless

[Matan Faragi]

Hi,

 

I'm not sure its the right place but at any case i will describe my issue here and maybe you will be able to help:

Recently I bought a a TV and a sound bar, and i have some issue from the moment i get the TV.

TV model - LG 55LB679Y with latest firmware version i have at my country (Israel) - 04.30.16
SoundBar - LG NB4540

the TV connected to sound bar by "wireless simplink" feature 'LG TV' and TV connected to My Wireless router.

every 5 - 15 minutes, i have sound drops / Cutoff / stooped / Interruption, seem like the TV loose connection to sound-bar for few seconds or something similar, it's happen from any AV source im using HDMI, USB...

and the local re-seller replace the sound-bar to a new one (same modal off course) and i didn't help.  
i have try to troubleshot the problem in the last few weeks - but didn't succeed to solve it, and also the support / costumer service didn't have solution for this.

 

some steps i take when troubleshot this issue:
* different wireless configuration on router -  different channels, SSID, Security - issue still persist.

* another wireless router - issue still persist.

* working with optical cable to sound bar - just for testing - working ok, but i need the wireless feature working this the reason i bought sound bar and TV from the same manufacturer.
* disconnect the TV from wireless network - looks like it's working ok, but didn't had chance to test it for long time.

 

from my point of view looks like it's issue with wireless device on TV not able to to work in parallel with soundbar and wireless network for some reason, It could be caused bysoftware issue on WebOS or Hardware issue with this TV model.

 

I really hope you be able to help me or throw some light on this case.

Kind regards,
Matan

I have 55B6V and I'm having the same sound issues via optical out. Recently bought new active speakers and switched to optical and now the audio cuts out a couple of seconds every hour. Very annoying. I tried all settings and switching cables, nothing worked. I have the same problem no matter what source (PS4, Xbox, streaming or TiVO) I use. Getting desperate now, because I tried contacting LG customer service and they just told me to try different settings on the TV. Well, none of them worked and I notice I'm not the only one with this problem. Does anyone have a suggestion?

 

EDIT: Note that I don't have a soundbar but I have the exact same problem described in this thread /EDIT

The Soundbar I was using was from Orbitsound (Orbitsound A70).   Ultimately Orbitsound took responsibility (as LG seems to be not interested in finding a solution) and they applied an update for the Soundbar that looks to have mostly resolved the issue I encountered.   I do think that Orbitsound created an alternative fix to an issue that originated from LG.   To me it is disappointing that LG appear to have not actively sought to find a solution to this issue that is affecting a lot of customers.

That's great from Orbitsound, I really wish LG would try to do the same and find a solution. I'm at my wits end here. I don't want to sell my tv just because this annoying problem but so far no one has come up with a solution. I spent four hours googling this issue and it seems a lot of  customers are affected irregardless what receivers, soundbars or speakers they're using  - the thing they all have in common is using the optical output from a LG TV. Frustrating to say the least.

I had this problem ,the sound fades then returns to correct volume ,Contact your service provider ask them to check your router for faults, they will and as was in my case reset the router which solved the problem .

This is great. Please let me know if it continues to work.

Not sure why that worked as optical digital cables do not get lossey.    but hey it's something to try.

I had the drop out issue too lately and think i have fixed it . My TV is the LG 55 oled with the LG sound bar,   If the problem seem to happen only with a cable signal that is a strong indication the problem is with the cable box not the TV or sound bar.  My cable box is the newer 1TB  Technicolor unit with Spectrum.   Anyway I had it replaced recently and that is when the drop outs became very noticeable. I went into the sound settings and started checking  those. I found that Dolby Sound was for some reason set as off.  I turned that to on and the drop outs ceased so it seems the sound bar wants a dolby signal to be stable.    That's my experience.

Hi there, I had same issue with occasional connectivity loss between my OLED65B6P and LAS465B bar. Every few minutes, intermittently I'd lose sound for a second, or two. I replaced that thin cheapie optical cable that came with sound bar and used my old, fat Belkin optical cable. Over two hours of TV watching, not a single drop out. 

I think that thin cable is not insulated well, or maybe has low optical quality fiber in it, same as fishing line:)

Anyways, hope this helps. 

If that worked for you great.  I think the same optical glass is used in all of them but it is glass and if bent too sharply or jammed against something hard it will fracture and lose light conductivity.   I tried a new TOS cable and that did not help for my drop outs.  I thought  I had it fixed with a settings change but the problem came back!     I kept working on it and did find the reason for my dropouts though!!   It was RF interference or a weak signal that killed the Blue Tooth   connection.  I had to move the subwoofer to within three feet of the sound bar with nothing solid between them.  Now the audio is solid with no dropouts.  The same problem can be caused by several things.

Well, All you people having issue with dropping sound and come back after while. It's not issue with Tv, or router or cable or anything else.

It's stupid LG way of soundbar software setup. Even though you are connected to TV with optical or HDMI cable, issue still persist, due to

stupid soundbar wants to connect to internet wifi or LAN time to time. while attempting to connect, it drops sound and after unsuccessful

attempt, came back to normal sound until next attempt. It's no way to disable this and it's so stupid.

MAKW SURE YOUR LG IS CONNECTED TO WIFI/LAN, AND HAVE INTERNET CONNECTION. IT WILL BE HAPPY.

STUPID LG.

I have not had this issue anymore after switching from Frontier FIOS internet and TV to Comcast (gross) internet and Playstation Vue TV.

After turning on the LG SL6Y Soundbar exactly 30 minutes later, the sound becomes very quiet.  Tried all connection types.  After everything works for 30 minutes and fades.  Dropped settings.  Nothing helps.  Now on an optical cable. HDMI 2.1 did not help either, the same thing via Bluetooth.
 One of the masters on the forum says that because of the firmware.

Hello,

I have the same issues with my LG OLED65CX9LA and soundbar LG SPD7Y since a few days. Both connected via bluetooth and all apps from WebOS like Netflix, Disney or YouTube have sound interruptions every few seconds. Very annoying. Live TV from satellite works fine.

Do you have any solution? Connecting via eARC is not possible due to some optical reasons.

Softwares are updated on the newest version.

 

Thanks in advance.

Hello.  what TV do you have?  Try disabling bypass in the TV sound settings and setting HE-AAC there in the settings.
