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...enough of this “ X Score and X” stuff. Didn’t know I’d opened Pandora’s Box 😂. Besides the Kidd’s are probably saying “What the ???? is going on” 😂
