AppleTV4K Netflix & VideoPrime only background sound, no dialogue.
This problem was mentioned before, including an answer that referred to the online AppleTV manual. That seemed an easy solution, but the manual does not tell you how to adjust the balance between background sound and voices of speaking actors. I think this is impossible anyway.
The problem occurred out of nowhere, first with Amazon Prime, then with Netflix. No settings where changed, not on the AppleTV nor on Netflix or Prime.
When I stream to the AppleTV from a computer (using Firefox, login to Netflix, screen mirroring) there is no problem. So it seems that using the Netflix or Prime app on the AppleTV itself is the cause.
Anybody an idea? Referring to the manual is no help. Thanks, Jacques ( The Netherlands)
