How do I fix E/ARC sound issues after updating to tvOS 26.1 on Apple TV 4K?

Latest apple tv 4k with Lg g3..running the tvos 26. All fine and dandy. Some silly reason i decided to update Tvos 26.1, then boom all e/arc sound gone. Went into audio settings changed format to 16 bit and stereo. Pulled power and hdmi out to reset handshake.. still nothing. Had the same issue 2/3 updates previous. Changed lg sound in tb settings to tv (its working on everything bar E/Arc). Getting abit boring now….just a heads up guys.

Toggle eARC OFF → ON on the LG G3

On the LG:

Settings → Sound → Advanced → eARC

Toggle OFF

Wait 5 seconds

Toggle ON

In many cases, this re-triggers the EDID handshake correctly, even after tvOS fails.
