No audio on Memoji sent in Messages
I initially got a message that audio is in use by another app when recording a Memoji in Messages. I turned off all apps and relaunched Messages and tried to do it again. No message about audio being in use elsewhere, but the received Memoji message was silent with a no sound marker beside it. (speaker with a diagonal cross bar) Am I doing this correctly? Do I have to do more than stop and start on the button and then send near the Memoji? Have not found a relevant setting for the microphone.
