Apple TV 4K 3rd gen with Homepods scenario

[u/gallaxya]

Hello wonderful people,
Reaching out for a bit of advice regarding an issue I have with the following setup:
One LG webOS TV (LG55C9PLA) with an Apple TV 4K 3rd gen connected to it via the arc HDMI port with audio output to a pair of 2nd generation large Homepods. Whenever I stream something from my local network using the VLC app from the Apple TV I get a delay in audio vs. the video. Sometimes to mitigate I restart everything but it's a hit or miss scenario.
Has anyone found a solution to such a situation?
It's funny that this started some time ago. I had this setup since these 2nd gen Homepods appeared and it worked great but for whatever reason this started happening.

Thank you very much for any hint 🙂
