I found the issue that video and audio are out of sync gradually when playing encrypted HLS on iOS 13.4、13.5 Safari and macOS Safari (13.1).
When playback starts, the video and audio are synchronized, but they gradually start to misalign video and audio.
It does not happen under the following conditions
・ Under iOS 13.3
・ Unencrypted HLS
・ Playback with MSE Player (e.g. hls.js)
It's a sample page :
