Hi, Developers. I found the issue that pop noise occuerd when I play encrypted HLS in Safari on iOS/iPadOS 13 or later. It does not happen under the following conditions ・Under iOS 13.0 ・Unencrypted HLS It happened on the following devices. ・iPhone 6S (13.5.1, 13.6 Beta2) ・iPhone X (13.3.1) ・iPhone11 pro (13.4, 13.5.1, 14.0 beta1) ・iPad Pro(13.3.1) ・iPad mini (13.3.1) I thought it was the same problem as this ticket, but I didn't get the error mentioned on this ticket. https://bugs.webkit.org/show_bug.cgi?id=212131 I prepare sample video that the problems is happened. https://d29c8ds76t1544.cloudfront.net/dev_player/audio_sync/noise.html And this video is not happened.
