iOS 15.4 not sending audio when turning on/off camera




I am working on a videoconference app. As a base, I'm using the conference.html example and I'm noticing a weird behavior in an iPad 6th generation, iOS 15.4, both in Safari and Chrome not sending audio in certain circumstances:

- In desktop or another device, join a room and listen

- In the iPad

  1. join a room
  2. stream audio and video normally
  3. turn off camera -> audio is streamed OK, I can hear it in desktop
  4. turn on camera -> audio is NOT streamed, I cannot hear it in desktop

In Chrome in desktop and Chrome and Safari in an iPhone 13, iOS 16.0 it works as expected. I could not test it in other devices

Do you know where to start debugging?

Hi @Marc

I will give you some instructions to check WebRTC logs on the console. You can check if audio packages are sent or not. I hope it will be help.

On Safari:

  • In Preferences... -> Advanced, ensure Show Develop menu in menu bar is enabled.
  • In the Develop menu Settings, select the Console tab, then ensure WebRTC Logging is not Off (and so choose either Basic or Verbose).

At that point the Console will show WebRTC events and data structures.
