(HQPlayer) Try to run Network Audio Adapter (4.11) on MacOS Catalina (10.15.6) but failed.

Does the networkaudiod output show display information about discovery messages from HQPlayer? If not, it is not receiving those messages. One possible reason is that HQPlayer computer has multiple active network interfaces and the discovery messages end up on wrong link.

Broadcast is privileged operation and also bad in general (and that's why IPv6 doesn't even support such). So NAA discovery uses multicast packets destined to local network (non-routable) scope.

 

macOS doesn't like multicast bindings to fe80:: IPv6 automatic local addresses, this is why there is automatic IPv4 fallback. If you switch the IPv6 to use for example static IP's in fc00:: prefix it works.

I configured NAA machine's ipv6 network interface to "Unique local address", in my case, fd00:1::38f9:d349:f061 prefixlen 64.  Unfortunately, it dose not work and end up "Can't assign requested address" error and "Socket failure, falling back to IPv4-only!".

 

For me, fc00/64 prefix is working fine. But macOS is a bit painful and mysterious about IPv6.
