[Problem]: MAC address portion of raop service name changes to all zeros, shairport is then unselectable as output destination · Issue #1657 · mikebrady/shairport

After a while random shairport nodes become unavailable on the LAN as audio output destinations. It appears that the unavailable nodes have all zeros for the MAC address portion of the _raop._tcp. service name. If the shairport-sync service is restarted the MAC address in the name is repopulated correctly and the node becomes available again. The LAN is a mesh network with multiple Eero base stations, so I'm guessing that the nodes are probably hopping between them when the MAC address changes to all zeros.

I'm not certain that this is the root cause for why certain nodes become unavailable, but whether or not they have the full MAC address in the service name seems to map to whether they're selectable as an audio output destination or not. You can otherwise communicate with them normally.

The _airplay._tcp. service seems to be unaffected by this problem - it looks good whether the node is available or not. Both services contain the correct IP addresses in their text records.
