So, have a TCL Model#55S546 and I am streaming via a 4k Fire Stick. This is hooked up via an EARC to a Beam(Gen 1). There is a lip sync issue that is extremely noticeable. Any advice? On the sound setting on the TV, it's set to AUTO. Any advice is appreciated. Thank you!

Use the Pass Through setting along with setting eARC mode to OFF.
