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.

After support I had from LG, I found out that passthrough digital sound output works only with external HDMI devices and not with TV apps. I am not sure how can I remove or close a topic.
