The conninfo that authorises the RX stream goes out during the login,
before the audio socket exists — it has to, since it is what authorises
it. So the rig is told to send audio to :50003 while nothing is bound
there, gets an ICMP port-unreachable back, backs off, and the audio turns
up only when its own retry timer comes round: twenty to thirty seconds by
the operator's watch, ninety in one log.
It is sent once more the moment the port is listening, which is the same
message the session already carries — RS-BA1 repeats it too. The audio
dial moved above the pumps, because after ctrlPump is running the
control-stream auth state belongs to it.
