Hi @Mikael_Ollars,
Thanks for writing in and for sharing your report! Your Roon Server logs gave us a clear sign of the issue.
Here’s what we found. Your RAAT zones are unaffected, but on most 2.70 startups the multicast socket bind is failing, and that’s what takes AirPlay and Sonos discovery down together. The relevant piece from the log:
NetworkInformationException (10043): The requested protocol has not been configured…
at SystemIPInterfaceProperties.GetIPv4Properties()
at Sooloos.MulticastSocketHelper.Bind()
at Roon.Audio.UPnP.DeviceTracker.Start() ← Sonos
at Roon.Audio.Mdns.MdnsDiscovery..ctor() ← AirPlay
10043 is WSAEPROTONOSUPPORT, and it’s being thrown while Roon enumerates your network interfaces at startup. When the bind hits one of those it aborts, so UPnP (Sonos) and mDNS (AirPlay) never come up for that session, while RAAT/SOOD, which binds differently, keeps working. That lines up exactly with what you’re seeing.
Two things worth noting: this isn’t strictly new, the same exception appears on your 2.67 boots as well, and it’s intermittent (your first 2.70 start on the 8th actually bound cleanly and both devices appeared). So it’s tied to your interface configuration and startup timing rather than 2.70 removing anything.
Could you try the following on the FC10 and then send a fresh set of manualRoon Server logs to our uploader here?
- From an elevated command prompt, disable the unused IPv6 tunneling interfaces:
netsh interface teredo set state disabled
netsh interface 6to4 set state disabled
netsh interface isatap set state disabled
and disable “Microsoft IP-HTTPS Platform Interface” under Device Manager → View → Show hidden devices → Network adapters.
-
If SOtMLink and/or Npcap aren’t actively in use on this machine, disabling them will help too, each adds extra no-IPv4 bindings to the enumeration.
-
Restart Roon Server and grab a new log.
When the new log arrives we’ll confirm the MulticastSocketHelper.Bind / 10043 entries are gone at startup, that’s the reliable tell, more so than eyeballing whether the zones reappear, since the failure is intermittent.
Thanks again for the diagnostics on your end, it made this much faster to pin down.
