Arc and LG OLED TV sounds cuts in and out

starting a thread for all Arc and LG OLED TV owners that have the sound cutting in and out issue. there’s a thread with Samsung TV owners that had the issue resolved with the latest update released on 3/9. Can LG owners get some support?

    I had this issue, but I’ve gone 4-5 weeks without a dropout now, (touch wood).

    lg cx firmware 3.21.16 along with a different hdmi cable (Belkin ultra high speed) seems to have solved it for me, and I was getting these drops quite often when changing between devices or sources on the tv.

     

    Im actually a little hesitant about updating to the new Sonos firmware now.

      i’ve replace hdmi cables twice and it cuts on all of them. everything is up to date, LG C7, Apple TV and Sonos Arc.  if Sonos  support resolved this issue for Samsung, they should resolve it for LG TVs.

        Hope to solve at Sony TV too...

        I have tried 4 different hdmi cables and all my firmware is updated (arc, lg b9 and Apple tv 4k). But im still having complete audio drops when im switching source - that includes going from my Apple tv to the tv tuner but also when switching channels. 
         

        For now i can get the audio back by switching to the TV’s speakers and then after a few seconds it will change to hdmi and that will “trigger” the audio to “come back” to the arc.

        Have the same issue with LG CX and Sonos Arc in 5.1 configuration. Switching inputs often makes the sound stop completely. Only a reboot or switching inputs a few times helps sometimes.

        This was my issue, it’s really strange how it seems fixed for me now, really odd. As I said above latest cx firmware and new hdmi cable and not had dropout for over a month.

        I have the slightly older LG C9 OLED running on LG firmware v05.00.10 and no audio dropout or lip-sync issues at all with that current build.

        I’m running the TV with the Sonos Arc, surrounds & Sub connected via HDMI-eARC. The digital sound out is set to ‘pass-through’, rather than ‘Auto’. The HDMI input audio format is ‘Bitstream’. DTV audio is set to Auto (default).

        Do you have any hardware connected? Apple tv? 
         

        I have the same settings and im having audio drops 5-10 a day. It happens when i switch source and i have a theory its connected to audioformat. So when i switch from 5.1 to 2.0 the audio drops completly and i have to remind the arc its getting a audio signal.

        Yes, I have an Apple TV.  Why hasn’t Sonos Support been on this thread like the Samsung thread?
