LG C2 Oled Connected to Samsung HW-Q800B Soundbar: Sound delays to respond during movie pause/unpause on TV streaming Apps like Netflix and Prime Video when sound output is set to Passthrough

Hello, 

I have recently purchased an LG C2 Oled TV which I connected with my Samsung HW-Q800B 5.1 soundbar via eArc HDMI. When I select "Passthrough" as a Digital Sound Output on LG TV sound advanced settings, there is an obvious sound response delay around 3 seconds when I pause and unpause the movie on Netflix or Prime video streaming apps on LG TV. For example, when I start the movie, the video starts and sound starts 2-3 secs later. When I pause the movie, the sound continues for 2-3 secs after the video has been stopped. There is no any lip sync issue, just this response delay of the sound from the soundbar. This happens only on LG TV Apps. If I connect to an external HDMI device such as AMAZON Fire Stick 4K, there is no such sound delay issue neither on Netflix neither on Prime Video. 

Thus, the problem seems to be on LG TV apps.

If I change the Digital Sound Output to "Auto" instead of "Passthrough" the issue is gone but sound quality is not as good as with Passthrough selected. So I do not want this to be my option.

I would appreciate if someone could come with a solution on this.

      Has anyone noticed a strange behaviour with using an LG soundbar with an LG TV using ARC? When I first had the TV, it worked a treat. When I started the TV, it would wake up the soundbar and all was good. However after one of the software updates, the soundbar fails to start automatically. However, if I manually start it, the TV is happy using it as the audio channel. Also If I turn the TV off just after it has started then turn it back on, all of a sudden the soundbar kicks into life. Any idea what might be going on?
      Has no one else experienced this issue?

      Hi,
      I have just upgraded from an LG 06LF6300 TV to an LG OLED65C1PTB. On my old TV I could pause live TV for up to 90 minutes and replay at a later stage. 
      Can anyone advise if this feature is available on the LG OLED65C1PTB.
      Thanks 
      Sam

      CBS Catchup, Discovery+, POP player, and UKTV Play always need updating. Even seconds after you just updated them. It started doing this a few days ago.
      Who can I contact to get this fixed?
      Since the "apps need updating" notification now always appears when I switch the TV on, I now have no way of telling if anything really does need updating other than going into the LG content store, clicking Apps, clicking My Apps, and visually checking.

      Hey guys,
      While I have Sonos Beam gen2 connected to my LG 65C12LA via HDMI (eARC) I can’t select any other output device e.g. bluetooth headphones. I can technically select it in TV menu for like 5 seconds, and then output switched back to HDMI (eARC). Is it a bug or feature? 
      Thanks in advance!

      Good afternoon,
      I bought the LG C2 TV 30 days ago, everything works normally, now I went to use the ALEXA function:
      I have an ECHO DOT 3, I did all the procedures, I downloaded LG THINGS, I ACTIVATED THE TV SKILLS, the TV SPEAKERS, I linked the accounts EVERYTHING PERFECT, all commands work: TV ON/OFF, SOUND UP/DOWN, CHANGE CHANNELS, CHANGE DOORS, OPEN APPLICATIONS NETFLIX / PRIMEVIDEO, etc etc ....
      But after a while the TV is MUTE, NO SOUND comes out in ALL CHANNELS, IN ALL APPLICATIONS, not even turning the TV off using the CONTROL BUTTON or VOICE COMMAND does the SOUND work.... Only when I unplug the SOCKET does the SOUND come back... .but after some time the same thing happens.... I reset the television from the factory and redid all the procedures and the same thing....
      This also happens when I give a command to open NETFLIX/YOUTUBE the sound sometimes stops.
      I did the ALEXA only through the TV APP without the ECHO ... and the same problem happens.
      Could it be some SOFTWARE BUG? My TV is updated until TODAY 12/29/22 with the latest FIRMWARE, ALEXA is also updated.
