iOS 14 issue

There is a new issue for iOS 14 under following conditions:

  • Your app is designed for iOS & distributed publicly
  • Your app is sending audio (accessing the microphone)
  • Your app will stop calls during its lifetime but continue running for a longer time

In this case iOS might continue showing the microphone indicator light. This is due to an earlier iOS 13 hotfix to workaround a bug with older Unity versions that could cause a crash or audio to stop working if the audio layer is being shut down. By now the latest Unity 2018 LTS & Unity 2019 LTS version do not have this issue anymore.

You can deactivate the workaround by editing the UnityCallFactory.cs and replace the line

WebRtcCSharp.IosHelper.IosKeepAudioActive(true);

with

WebRtcCSharp.IosHelper.IosKeepAudioActive(false);

All future versions of the asset will contain this as well.
