Has IOS13 broken <audio> tags used as audio buffers connected to the audio context?

Question

We are currently developing a website that allows users to play simple audio tags connected to the audiocontext. We are aware of technical issues with IOS such as playback initi

Answer 1

Unfortunately, AudioContext.createMediaElementSource has been broken since the release of iOS 13. The bug was reported to be fixed in Safari Technology Preview 99: https://bugs.webkit.org/show_bug.cgi?id=203435, but it's still broken in the recent release of iOS, so a new bug report was filed which can be found here: https://bugs.webkit.org/show_bug.cgi?id=211394

Answer 2

This issue was mistakenly reported as fixed in iOS 13.3.1 (January 28, 2020). Nevertheless, as anyone can read from this WebKit bug report 203435, the problem is still there as of April 7, 2020, the release date of iOS 13.4.1.

The bug report doesn't provide any further information in regards to the estimated date this bug is going to be fixed. Sadly, 80% of iOS users (about 14% of the total mobile market, according to Statcounter) have been mistakenly incapacitated from using WebAudio on their devices for months, now.

What makes things worse for us developers is that Safari doesn't report any error. Thus, even trying to imagine a fallback is not possible or very hard, anyway.
