LG OLED Audio dropping out - ARC

[account_disabled]

Hello,


I am looking for any help or possible solutions to my home theatre audio issue.



Equipment being used:

- 2017 LG 65" OLED C7

- Denon AVR-1400H (via 18 mbs HDMI)

- Panasonic DMP-UB900 4k Blu-Ray

- PS4

- 5.1.2 Atmos speaker setup



When watching any high definition Netflix content (Atmos/Dolby vision, UHD 4K and even 5.1) and using the installed Dolby app pre-installed on the TV for Atmos and Vison sample content, the audio randomly mutes for 1-2 seconds. This could happen 10 or 5 times a minute. Ultimately makes it unwatchable and very frustrated when having such a high end theatre set up.



This error doesnt happen with free to air TV, content from USB, gaming consoles or the 4K Blu-Ray.



I have contacted LG for support as I feel it is a TV issue rather than receiver or hardware issue, as it only happens with apps built-in to the TV.



Has anyone else experienced this or similar?


Thank You!!!



I didn't find the right solution from the Internet.
