Created attachment 462787 [details] small sample to reproduce the issue If I creating and interacting with AudioContext it is brokes local audio tracks. Steps: - create audio context - do something (e.q. createGain) - get local media - assing to video element Actual result: - no audio and MediaStreamTrack ended due to a capture failure after few seconds. And you cant get any audio track anymore at this page I created small sample to reproduce the issue. Iphone 14 Pro, iOS 16.0.2 Issue is reproducible only on iphone 14 Pro (we tested on 2 devices) Don't reproducible on iphone 13 pro and iphone 12 pro

we have same issue on iphone14 pro and iphone14 pro max. We have tested on 4 devices. When you have this issue, you could not create any new audio tracks at this page and another tab page. This is my demo's URL: https://www.neil9111.com/rtc-wtf/webaudio.html You can click these buttons in order of 'play','resume webaudio','stop','play', eventually you won't be able to hear it on iphone14 pro, iphone14 pro max. But it works fine on other devices.

I can confirm that for my application it seems to work like a charm again with 16.2 beta. I tested multiple times in several combinations and I always got the expected result. So please release 6.2 tomorrow ;-)
