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

We have same issue
Comment 3 Vincent 2022-11-21 04:53:35 PST 
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.

Can you reproduce in latest iOS 16.2 beta?
Comment 7 Davy De Durpel 2022-12-12 03:03:02 PST 
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 ;-)

Marking as configuration changed.
