Description Sarmistha 2020-04-23 18:45:04 PDT

No audio from participant who is on iPhone with iOS 13.3.1+ in a webrtc visit. This issue is seen on iPhone 11 and iPad. The issue is intermittent. The packet capture shows no output from the iPhone. Mobile browser refresh is not resolving the issue. 

Any known issue or any fix coming soon?

Sarmistha, would you be able to gather some more information, or provide some kind of repro case. You can gather WebRTC logs that might help as well.

Youenn, we are running into this issue on iPhone running iOS 13 and on iPads on https://jaya.jitsi.net. The audio doesn't start when we join the call. However, if we tap on the camera icon on the browser tab twice to disable and enable it, audio starts working most of the time.
