sometimes after rebooting RoPieee it is shown as a new Squeezelite client with MAC address 00:00:00:00:00:00. I experienced this with other operating systems in the past and it seems to happen if Squeezelite starts before the network connection is ready. A fix could be to pass the MAC address to Squeezelite with the -m parameter. It‘s annoying when this happens because as a new player all player settings like alarms etc. are not applied.
Can you send me feedback of one of those units when it happens?
And it is still very strange: mac addresses of interface(s) are there, even if the connection is not setup. Unless the software uses a rather primitive way of fetching the mac address…
