As Colin mentioned this smells a lot like a race between device node
creation and PA picking the device up.

Could you please run "udevadm monitor --udev -ssound" and paste the
output it generates when you hotplug here? This should tell us if the
order in which the devices are created. Might be a good idea to run it
multiple times to 'verify' that the order is deterministic.
