Apple TV 4K audio sync

When watching recorded OTA ASTC 1.0 HDHR programs at 1.25 speed the audio and video become out of sync. This is not a problem when using my Apple TV HDs. I tried using the experimental audio driver and the default driver. Turned off surround sound. This has been going on for some time.

Apple TV HD model or 4K model ?

The audio sync issue is only with the AppleTv 4K. No issue with the HD AppleTv hardware.

Ok I found 2 ways to fix the audio sync issues at the 1.25 playback speed. Either lower my resolution to 1080 or use the legacy video driver for 4K HDR.
