Has anyone else noticed that, as of about three weeks ago, Netflix audio is about ⅒ s, maybe twice that, ahead of the video? Netflix’s suggestion to change the audio format to Dolby Digital 5.1 improves the problem slightly but not all the way. Amazon Prime, for example, does not have that problem. I also played Audio Video Sync Test in the YouTube app, which showed perfect video-audio synchronization. If I use my receiver to correct for Netflix's problem, it will be off for all other video content played on my Apple TV (4K, 1st Gen).
