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.
