Following on https://bugs.webkit.org/show_bug.cgi?id=231105 which was MacOS specific, we have the same AudioContext issues: - If page is backgrounded, AudioContext will be stopped even though AudioContext is not used directly for playing audio - AudioContext might be resumed by web page in case it can autoplay (for instance if page is continuing to capture audio, which allows to continue playing audio).

As spotted by Cameron, media/auto-play-web-audio-in-about-blank-iframe.html is failing on bots after this change.

Thanks for fixing this. What iOS release can we expect this fix?
> Thanks for fixing this. What iOS release can we expect this fix? I'd also like to know the targeted iOS release. It's become a critical issue for us.
Oh no not again... almost same problem was introduce iOS 13 (webaudio stops when app is in background), it took one year to fix back then... https://developer.apple.com/forums/thread/121822 Please, this is CRITICAL, how can we develop a real music app with WVWebView if the audio stops in background? ... The problem doesn't happen on iOS Safari. I am questioning the QA team who validated this release because the problem is so obvious.
Same bug in iOS13 > https://bugs.webkit.org/show_bug.cgi?id=203293, fixed in iOS14 and introduced again in iOS15... please this is a big issue...
@youenn fablet, Is this critical bug fix will be shipped on iOS16 only? if so it won't be accessible for all iPhones prior to iPhone 8, which is a big problem for wide adopted apps. Could you please release the fix in iOS15? iOS14 is not affected by this bug. Thanks!!

@youenn fablet thank you for the reply and the fix!! but tell me if I am wrong, will this mean that the iPhones 6s/7/SE1 and many iPads will never be able to play background webaudio? (= making it unusable) If so, this would be a big problem because it has never happened to have a "hole" in the support of webaudio... :/
Just another upvote: it would really really be great if this fix could be merged into a 15.x release! Thanks for your consideration.
@youenn fablet, I just installed iOS 16 Beta 1 as you adviced, the fix is not there, WebAudio keeps stopping if app go to background... :'( Also I have issue with WebAudio with bluetooth, it is completely buggy. I don't know if you were aware of it... (I am french too :)
ps : test it by yourself if you need : https://apps.apple.com/us/app/youdj-mix-music-now/id1459666155 (desktop version is a popular DJ app : https://you.dj)
Just to let you know, the fix is still not included in iOS 16.1 beta :'(
The bug is still present in iOS 16.1 release. Tested on an iPhone 11 Pro demo playing various games on https://nj-casino.goldennuggetcasino.com/
The bug is 18 months old and it is still present in iOS 16.3, discouraging... Also iOS 16.3 introduced a new bug! Now the silent switch is also muting WebAudio... The WKWebView behavior should match native apps for audio, otherwise it is useless and confusing. I have open a new bug thread, these issues are too blocking : https://bugs.webkit.org/show_bug.cgi?id=237878
Sorry the new bug thread is : https://bugs.webkit.org/show_bug.cgi?id=251532
