Word fo warning to others who might try the replaceTrack workaround. I'm seeing some serious delays post unmuting in certain cases on Chromium-based WebRTC engines (Safari included). Firefox seems unaffected. So don't go changing all of your muting code to replaceTrack, it might cause some other painful issues, best to keep this to iOS 13 only.

FWIW here is my workaround code:

const audioTrack = this.mediaStream.stream.getAudioTracks()[0];
const audioSender = this.pc
  .getSenders()
  .find(
    s => (s.track && s.track.kind === "audio") || s.track === null
  );
audioSender.replaceTrack(action.isMuted ? null : audioTrack);

And remember to stop doing track.enabled whereever you might do that in your code.
