Microphone not reconnecting upon application unpause on iOS

I can see other players, I can hear other players, but they can't hear me.

iOS
join room - using autoconnectandjoin checkbox on PhotonVoiceNetwork
swipe to go to home screen, and come back
no more mic

in OnApplicationPause
tried a bunch of things (resetting mic, disconnecting/reconnectnig, never comes back?

What am I doing wrong!?
