Arc sound stopped on LG G4

Hi All,

Yesterday my sound stopped working from the Arc.  After following a few suggestions of toggling things off and on, restarting tv and arc (fixed it for about a minute then dropped again), I had to reset it.  Only then it appears to be back on although haven’t had it on for longer than 15 mins today to see if its a fix.  

Been working fine for over 2 years.

Why would it do this?  Is it likely developing and problem or could it simply be a one off handshake issue?

Strangely, when I tried to run the SONOS radio instead of TV, the sound came through the rear surrounds.

Factory resets are typically a last resort and only recommend in extreme circumstances at the behest of Sonos Tech Support. If there was an issue with your Arc the Factory Reset erased any information that would have been useful in a diagnostic to Sonos Tech Support. If the issue returns run a diagnostic, make note of the reference ID (don’t post it in the community) and call Sonos Tech Support.

Your issue could have been a handshake issue. Sometimes a hard reboot sequence may resolve the issue:

  1. Pulling the power cord while TV is on
  2. Hard reboot of Arc
  3. Giving the TV power again
  4. Powering up the Arc

Music playing through the rear speakers in a Sonos HT setup is normal (ambient or full stereo *). Unless you’re saying no sound was heard from the Arc. Was that the case? If so you need to run the diagnostic and call Sonos Tech Support as the Factory Reset did not fully resolve the issue.

 * Music volume such as Ambient (soft) or Full Stereo can be set in the App.

OK….

  • Is the Play 1 being used as a surround speaker for the Arc?
  • Can you stream music to the Arc when TV is off?

Sonos support are saying I need to plug 2 devices into my router! Why? It's been OK for 2 years. 

Tried changing the channel in sonos net but it dropped sound soon after. 

I'll be ringing them again tomorrow. 

Why not try it first, and see if it helps? Then work out the “why?”.

    Why are you on SonosNet?

    That's how it set itself up I guess. If not, how will the speakers connect? 

    Is it safe to disable it? 

    Is sonosnet likely to cause a problem??

    I see you have a Play 5 (Gen 1).  So you are on the older S1 app….Correct?  Which Sonos device(s) are on Ethernet?

    No I don't have that now. I'm on latest app with arc, sub, 2 play1, a play3 and an ikea speaker. An update was done while onto sonos support. 

    Arc is on ethernet and now one of the 1s is.

    It's not disconnected again yet since connecting the 1.

    What I don't understand is why this has suddenly happened, needing the 1 to be connected.

    Dont really want cables in view.

    If you disconnect all Sonos devices from Ethernet and let them all connect to your WiFi does that work?  You should not need Ethernet with a modern WiFi network in the home.  What is your network?
