Ahhhh… sheesh. Welp, this just in from the “I’m an idiot” department: I was testing SlimServer last week, hated it, and deleted it. However, unbeknownst to me, it seems to have fired up its very own mDNSResponder, which I just noticed was still running. 😳 Beware of SlimServer.
Its dead now. And mt-daapd seems to be running just fine. Glad this was an error on my side. Ron, you must be sick of answering multicast questions…
