Additional info:

Not sure if this is related but at least two of my cast devices weren't showing up at all. When I checked my home app they showed as linked but not active. I rebooted both devices from the Home app and then restarted HA. Both showed up immediately.

Now, I wasn't getting the Address already in use error, but I would suggest trying the same steps to see if it helps.

Do you have any other services on your machine that are running a zeroconf service?
