Based on Sentry logs, this affects ~5% of our Safari 15 users and 100% of those are on macOS 10.15.7. We have no reports of this issue on Big Sur or Safari 14. It sounds like other developers are hitting this issue as well: https://stackoverflow.com/questions/69452545/safari-15-fails-to-decode-audio-data-that-previous-versions-decoded-without-prob I'm not sure what additional information I can provide – the error callback is called with `EncodingError: Decoding failed`, but there's no additional information or logs. 1805335 1 cdumez 2021-10-16 18:06:24 -0700 Yes, there was indeed a regression specific to macOS 10.15. It was fixed in Bug 230974. *** This bug has been marked as a duplicate of bug 230974 *** 1839185 2 Lmssrinivas 2022-02-09 08:38:17 -0800 I am in MacOS Catalina version and Safari ~15 and still decodeAudioData doesn't work? Is there a timeline on when it is supposed to be available?
