Audio stops when receiving a carrier call or Siri is activated

[yllfejziu]

Description

Audio stops upon receiving a carrier call (starting another audio on youtube or anywhere, activating Siri) and doesn't continue after rejecting / finishing the call. The audio is lost whenever an audio session interruption is occurring and it's never reconnected (the video tracks are working fine).

Steps to Reproduce

1. Connect to room with other participants
2. Activate Siri or have someone call you

Expected Behavior

Audio reconnects back to room and you can hear other participants as well as they can hear you.

Actual Behavior

Audio doesn't reconnect after interruption and other participants cannot hear you and you can't hear them.

Reproduces How Often

Everytime

@yllfejziu Thanks for reaching out. Are you using CallKit in your app? Here is example how to use callkit with the app for multicall/audio management.

@piyushtank integrating call kit solved the issue.
