Sound Cutting Out When Using LG OLED 77CX eARC Setting

I recently purchased a LG OLED 77CX and connected my Sonos Arc. On the TV, there’s a setting to turn on the eARC capability. However, when I turn on the eARC capability, the sound through the Sonos Arc cuts out every few seconds and comes back on within a second or two. I thought eARC capability was the newest technology; however, it seems something isn’t connecting properly between the TV and Sonos Arc.

The only setting I was able to change was the Digital Sound Out which I changed from Auto to Pass Through. When I turned the eARC on I thought that was the solution because when I started to watch a show on Amazon Prime the sound didn't cut out. Unfortunately, when I went to a show on Hulu the sound started to cut out so I switched everything back.

Since everything else seems to be working and you don’t need eARC functionality with your current setup, just keep eARC turned off. Hopefully LG and Sonos will have it fixed before you need to turn it on in the future if you ever decide to add an external device that requires eARC.

Thank you. That seems to be my best choice right now.
