I’ve started to experience audio sync issues following the update to tvOS 18.4 and recent Infuse updates. The problem only occurs if the video is paused long enough for the screensaver (aerial) to kick in. Then when resuming the video the audio is noticeably out of sync. If I stop the video completely and then play with resume, the audio is back in sync.
I do have frame and dynamic range matching enabled and so I suspect the issue may be caused by this mode switching from screensaver to video.
ATV is connected via HDMI to a soundbar which is then connected to the TV.
