From the documentation for AAudio, when a device is disconnected all we can do is stop it. However, we cannot stop it from the callback - we need
to do it from another thread. Therefore we are going to use an event thread for the AAudio backend to do this cleanly and safely.
When we get an error, we'll assume that the stream is in an erroneous state and needs to be restarted. From the documentation,
