There’s a bug with infuse that causes videos to desync when they are sped up while using Bluetooth headphones (AirPods in my case) whenever you pause and play the video.
Steps to reproduce
Connect your AirPods to Apple TV. Play a video at an increased speed (e.g x1.5)
Pause the video using the Play/Pause button on the Apple TV remote. Resume the video by pressing the same button once again. The audio should now be desynced from the video. The desync only occurs when using AirPods (I’m assuming other Bluetooth headphones as well), never when using the tv speakers.
