Description PhungDuong 2022-06-07 21:30:10 PDT
With iPhone XS iOS 15.5, there is a new issue that started appearing.
If we let the iPhone auto-lock screen (after 30 seconds, 1 minute, etc.. depending on the settings display & brightness), the mic stops working, although the audio speaker still working.

Here are the steps to reproducer:
1. Open the link using WebRTC: https://it.dev-akameet.link/video/room/testbug or https://meet.jit.si/testbug
2. Join meetings and on the mic (off camera to auto-lock screen)
3. After an amount of time, iPhone will be locked screen.

Expected: Can hear and speak normally.

Actual: Can't speak via the mic, but can hear the others in the room.

Note: If unlock the Iphone's screen we can speak via the microphone can work normally.

Thanks for filing, I've not been able to reproduce this on iOS 15.6 beta 3 (19G5046d). Does this issue reproduce for you on that build?
