However when passing a PCM WAV file to both an <audio> element and Web Audio, it correctly decodes and plays the file. Observed result: canPlayType() returns empty string Expected result: canPlayType() to return "maybe" or "probably" 1828157 1 webkit-bug-importer 2022-01-04 17:05:56 -0800 <rdar://problem/87122702> 1871787 2 acase 2022-05-25 11:27:28 -0700 Hey all, this is becoming a big challenge and causing us to have to recommend using any other browser. But Safari has the best video codec support with HEVC and PRORES -- commonly with wav/pcm audio... thus our application can't trust if it can play the files or not. 1987507 3 bfulgham 2023-10-25 13:01:19 -0700 This should be fixed in Safari 17. I checked on a recent macOS Sonoma system and am able to play the PCM WAV example (and others on the site). 1987511 4 bfulgham 2023-10-25 13:03:27 -0700 Note: The cause of this bug was outside of the WebKit source code, so I am marking this as 'Configuration Changed'.
