How can I fix Apple TV Enhanced Dialogue volume issues?

Don't have access to Hulu, but tested on Paramount Plus and Netflix and it worked as intended. If the issue persists though I would contact Apple support so they can investigate.

I had a problem with the enhanced dialogue too, but only while watching Apple TV plus. The audio would randomly drop out completely to silence for about a second or two. It was strange because the audio drop didn't happen while viewing anything other streaming service on the Apple TV. I disabled enhanced audio and all was fine again. Odd.

It seemed to happen on all Apple TV shows (Silo, Severance) and on two different Apple TVs. Yeah! I was hoping it would be a know issue to Apple and they'd fix the bug in software. I'll give it another try and see.

That is strange, was it on a particular show/film or across different content on Apple TV Plus? There was recently an update pushed out so you can always try again and if it persists contact Apple.
